Pure Zen Tea Tumbler with Infuser

Yes, this is one of the most praised features. The double-wall borosilicate glass construction genuinely keeps the exterior cool even when filled with piping hot tea, so you can comfortably hold it without burning your hands. Plus, it creates this beautiful floating effect where your tea appears suspended in mid-air.

Here's the honest truth: this tumbler can be leak-proof, but it requires some attention to detail. The gaskets and O-rings need to be properly aligned and the lids carefully threaded. Many users have zero issues, but others find they need to check the seals regularly and tighten everything just right. If you're meticulous about screwing lids on fully and maintaining the gaskets, you'll likely be fine. If you tend to rush, you might experience occasional drips.

Yes, and this is actually a clever design feature. You can position the stainless steel infuser in either the top or bottom compartment. Start with it on top while brewing, then flip it to the bottom when you're ready to drink - this stops the steeping process and prevents over-extraction. It gives you real control over your tea's strength without having to remove a messy infuser.

It should fit in most standard car cup holders, and several users specifically mentioned using it during their commute. The included neoprene sleeve even has a carrying loop for easy transport. Just keep in mind that the tumbler holds about 10-13 oz of actual drinkable liquid due to the double-wall design, so it's sized for a generous cup of tea rather than a huge travel mug.

Yes, and this is a major selling point for people who want to avoid plastic taste or chemicals in their tea. The tumbler is made entirely of borosilicate glass and stainless steel - no plastic touching your tea. The only plastic is in the exterior lids, which don't contact the beverage. Tea enthusiasts particularly appreciate this for preserving the pure, clean taste of premium loose leaf teas.

It's actually easier than most because both ends unscrew completely, giving you full access to the interior. You can reach every surface without awkward bottle brushes. The glass components are dishwasher safe, though you'll want to hand-wash the stainless steel infuser and check the gaskets regularly to prevent any mold buildup. Just be aware that it does require daily thorough cleaning - this isn't a rinse-and-go situation if you want to avoid issues.
