FLASKE Tumbler: The Best Stainless Steel Tumbler Cup


A sustainable stainless steel tumbler cup makes drinking on the go even more convenient.

There are many tumbler cups on the market but, like reusable coffee mugs, the best travel tumblers are made from stainless steel. They’re stronger, healthier, and better looking than plastic tumblers. They help to reduce waste too. It’s no wonder that stainless steel tumblers are so popular! 

But, before I talk about what to look for in the best travel tumbler, let’s start with why you should buy a stainless steel tumbler in the first place.

Eight reasons to buy a stainless steel travel tumbler

1. It’s durable

Stainless steel is a sturdy material that’s built to last. You can drop a stainless steel tumbler without fear of it breaking, and your drinks will still be insulated even if you scratch the surface. If you don’t lose your stainless steel travel tumbler, you may never need to buy a second one. 

2. It’s BPA-free and chemical-free

Unlike many plastics, food-grade stainless steel doesn’t contain BPA and, unlike plastic, it doesn’t leach harmful chemicals into your drinking water, even if you fill your stainless steel tumbler with hot liquids. That makes it a safe container for drinks

3. It keeps your drinks hot or cold

Stainless steel tumbler cups with a double wall insulate your drinks and keep them at the right temperature. The FLASKE Tumbler is insulated for both hot and cold beverages so you can use it all year round. 

4. It’s comfortable to drink from

What makes a tumbler cup different from a coffee mug is its straw-compatible lid. You can sip from a tumbler cup, with a reusable straw, just as you would sip a glass of homemade iced tea or green smoothie. Or, if you prefer, you can remove the lid to drink from a travel tumbler like a regular tumbler glass.

5. It’s easy to clean 

Stainless steel tumblers are easier to clean than reusable water bottles because they have a wide opening. This means that you can fill it with all kinds of beverages, from smoothies to alcohol, without the risk of growing bacteria. Stainless steel is also more resistant to bacteria than plastic.

6. It’s perfect for summer cocktails (and other iced beverages)

It’s thermally insulated, has a straw-compatible lid, and a wide enough opening for large ice-cubes. Tumblers are the best zero-waste travel container for cocktails and iced beverages. Want to know what else you can drink out of a tumbler? Read this post

7. It helps the environment

When you buy one reusable tumbler cup, you minimise on the go plastic waste and prevent hundreds of disposable cups from going to landfill. Because, so much plastic waste ends in the ocean, by investing in sustainable drinkware from an eco-friendly online store, you also invest in environmental protection. When you buy in a FLASKE Tumbler, you actively support The Ocean Clean Up

8. It’s stylish

Aside from helping the environment and taking care of your health, you can impress your friends and family. Tumbler cups are chic, and being sustainable is trendier than it’s ever been. Travel tumblers aren’t just useful for you; they’re also an excellent gift for your eco-friendly (and your not-so-eco-friendly) peers. 

What is the best material for a tumbler cup?

The best material for portable drinks containers, including tumbler cups, reusable water bottles, and coffee mugs, is 18/8 food-grade stainless steel. Stainless steel is better than plastic and aluminium for all types of drinks containers for several reasons. Stainless steel is free from toxic chemicals; it doesn’t require a liner and won’t contaminate your drinking water even after years of use. Stainless steel is also extremely durable, so you can save money and go plastic-free at the same time. Because it’s safe to put boiling water into a stainless steel tumbler, it’s easy to kill bacteria and stay healthy.

What is the best reusable tumbler cup?

The best reusable tumbler cup should be:
  • Made from high quality 18/8 food-grade stainless steel.
  • Have a leak-proof and straw-compatible lid.
  • Have double-wall insulation that keeps drinks hot for up to 6 hours and cold for up to 12 hours.
  • Have a wide opening so you can add ice cubes in the summertime.
  • Come in a convenient size.
  • Affordable
Other things to consider when you buy a reusable tumbler cup:
  • The colour or design, you want a personalised tumbler that you’ll love forever. 
  • The brand, if you want to help the environment, be sure to purchase from an eco-conscious company that supports environmental initiatives.
