Plastic mates are the most affordable and widely available option, commonly found in kiosks, souvenir shops, and street markets throughout Argentina. Mass-produced by injection molding, they come in countless bright colors — often translucent, giving them a candy-like, colorful look that stands out from more traditional materials.
Why Choose Plastic
Plastic mates are the cheapest way to get started with mate, making them a popular pick for tourists, casual drinkers, or anyone who just wants to try the ritual without committing to a pricier option. Like silicone, they’re non-porous, don’t need curing, and are ready to use right out of the package.
Things to Consider
Plastic isn’t as durable as stainless steel or as travel-friendly as silicone — it can crack or become brittle over time, especially with repeated exposure to hot water. It also doesn’t retain heat well, and most mate drinkers see it as an entry-level option rather than a long-term choice. Look for mates specifically labeled food-grade or BPA-free, since quality varies widely between manufacturers.
Care and Maintenance
Rinse with water after each use; avoid very hot water for prolonged periods, since repeated heat exposure can warp or degrade lower-quality plastic over time. If you notice cracking, cloudiness, or a persistent odor, it’s time to replace it — unlike metal or ceramic, plastic isn’t built to last for years.
