New from Haers: A Custom Yerba Mate Set for Brands
In December 2022, Argentina’s national team reportedly travelled to the World Cup in Qatar with around 500 kilograms of yerba mate in its luggage. After the final, one of the images that travelled furthest was Lionel Messi arriving home at dawn with the trophy in one arm and a mate in his hand.
For much of the world, it was a first look at the drink. For anyone in Buenos Aires, Montevideo or Asunción, it was simply an ordinary morning.
Mate has been part of daily life in South America for centuries. What has changed is where people drink it: on the commute, at the desk, in the park, on long drives between cities. That shift asks more of the gear people carry.
That is the thinking behind our new yerba mate kit: a 1000 ml vacuum flask, a 280 ml insulated mate cup and a spoon-style bombilla, designed together as one set and built for brands to make their own.
From Gourd to Go: Why Mate Needs Better Gear
Anyone who drinks mate knows the kit: the yerba, the cup, the bombilla, and a termo tucked under one arm. The cebador refills the cup and passes it around the ronda, again and again, until the yerba has given all its flavour.
Much of the traditional gear was made for the kitchen table. A natural gourd has to be cured before first use, and if it is not dried properly it can grow mould or crack. A flask designed for coffee often pours too fast, flooding the yerba instead of wetting it gradually. And three pieces sourced from three suppliers rarely match in colour, finish or quality.
For a brand, none of these are small details. Each one shows up later as a customer complaint, a return, or a range that looks inconsistent on the shelf. We designed this set so the three pieces arrive as one product: one SKU to quote, merchandise and package, with every part made to the same standard.
What’s in the Set
| Component | Capacity | Dimensions | Key details |
|---|---|---|---|
| Vacuum flask | 1000 ml / 34 oz | 10.9 × 9 × 31 cm (4.3 × 3.5 × 12.2 in) | Double-wall vacuum insulation, cylindrical pouring spout, detachable leak-proof lid, folding carry handle |
| Mate cup | 280 ml / 9 oz | 9 × 9 × 9.5 cm (3.5 × 3.5 × 3.7 in) | Double-wall vacuum insulation, tapered body, three exterior textures |
| Bombilla | — | — | Spoon-style filter, easy to rinse |
The flask and cup are made from food-grade 18/8 stainless steel, with BPA-free components. Both are vacuum insulated, keeping drinks hot for up to 12 hours or cold for up to 24 hours.
Standard colours: cream white, light pink, light purple, light blue and black.
Designed Around How Mate Is Poured
Mate is not tea poured into a mug. The way water meets the yerba shapes the taste of every round, so we started from the pour and worked outward.
A spout made for the cebador. The flask uses a cylindrical pouring spout, in the spirit of the pico cebador many South American drinkers look for in a termo. It delivers a narrow, controlled stream, so the water can go in along the edge of the cup and wet the yerba a little at a time instead of soaking the whole bed at once. The yerba holds its flavour for more rounds.
The right temperature, not the highest. Mate is usually prepared with water at around 70–80°C (158–176°F); boiling water scorches the leaf and makes it bitter. What matters is that water poured at the right temperature stays in that range across a long ronda, rather than drifting to lukewarm by the third refill. Double-wall vacuum insulation is what keeps it there.
1000 ml for a full ronda. Enough to keep a group’s mate going for a long sitting, or one person’s through a working morning, without hunting for a kettle.
A cup that needs no curing. The 280 ml mate cup is double-wall vacuum insulated, so the last sips stay warm while the outside stays comfortable to hold. Stainless steel needs no curing and does not absorb moisture the way a natural gourd does, so it is ready from the first use and simple to keep clean. For brands, that is one less instruction to print on the box and one less reason for a return.
Small details for daily carry. The spoon-style bombilla rinses clean quickly. The flask lid detaches fully for washing and seals against leaks in a bag. A folding handle makes the flask easy to carry, and the tapered cup sits naturally in the hand.
Three Textures, Rooted in Matero Culture
In South America, the mate cup is personal. Many people own several, and the one they carry says something about them. We offer the cup body in three textures, each with its own place in that culture:
- Leather grain echoes the leather-wrapped mates (mate forrado en cuero) that have long been part of the tradition. A natural fit for heritage-led brands and yerba producers.
- Wood grain recalls the carved wooden mates found in homes across the region. A warm, natural look for gift and lifestyle ranges.
- Silicone sleeve adds grip and a softer touch. A modern, outdoor-ready option for younger and active consumers.
The five standard colours are a starting point. We match any Pantone colour for the flask and cup body, and textures can be chosen from our existing surface finish options. Your logo can be applied by silk screen, laser engraving, heat transfer or digital printing; see how we apply custom logos for details.
Because this is sold as a set, packaging carries more weight than it does for a single bottle. It is often the first thing a shopper sees, and for gifting it is half the product. We produce retail-ready packaging including colour boxes, gift boxes, cylinder boxes and display packaging, designed around how your customers will buy it.
Materials and How We Validate
Both the flask and the cup use 18/8 stainless steel with a seamless, one-piece inner liner, so there is no internal seam where residue can collect. All components in contact with drinks are BPA-free.
Haers has helped draft 47 industry standards, including GB/T 29606, the Chinese national standard for stainless steel vacuum cups, and runs a CNAS-accredited in-house laboratory recognised in more than 90 countries. Our qualification programme for vacuum drinkware covers, among other tests:
- Heat retention: filled with boiling water, sealed once the water measures 95°C, and checked after a set number of hours at controlled room temperature.
- Leak resistance: tested with both hot water and ice water, shaken and then left lying on its side.
- Impact: dropped and swung against hardwood, after which the product must still seal and insulate.
- Durability: parts that open often, such as lids, are cycled 10,000 times.
- Handle strength: loaded with six times the weight of a full product.
- Odour: checked with hot water after sealing.

- MOQ: 3,000 sets.
- Made to order: the set is not held in stock; every order is produced to your specification.
- Lead time: depends on quantity and the level of customisation. Our sales team will confirm it with your quotation.

- Sampling. We produce samples for your review and approval.
- Production. Mass production under our standard quality control.
FAQ
Can I order the flask or the cup separately?
This product is sold as a complete set only. If you are looking for standalone flasks for another line, browse our stainless steel flask range.
Is the set suitable for chimarrão or tereré?
The 280 ml cup is sized for mate as it is commonly served in Argentina, Uruguay and Paraguay. Chimarrão in southern Brazil is usually drunk from a larger cuia with hotter water, so if Brazil is your main market, tell us at the quotation stage. For tereré, the flask keeps drinks cold for up to 24 hours, and the vacuum cup helps hold the chill.
What water temperature should we recommend to our customers?
Around 70–80°C (158–176°F). Boiling water burns the yerba and makes it bitter. Many brands print this guidance on the packaging or an insert card.
How far can colours and textures be customised?
Fully. Beyond the five standard colours, we match Pantone colours for the flask and cup body. The cup texture can be leather grain, wood grain, silicone sleeve or another finish from our existing range.
What is the MOQ?
3,000 sets per order. The set is made to order and is not available from stock.
