I have been loving this tea infuser bottle from Zen Bliss. No matter how safe people say their plastic water bottles all, I still worry about BPAs. This bottle is made from borosilicate glass, the same material Pyrex has been using for decades, so I am 100% confident it is safe. Also, when I wash it, I feel like it’s really clean. It is easy to wash too, both ends screw off and the infuser comes out. The silicone rings inside keep all liquids in, no leaks. I’ve been enjoying using it with the Zen Bliss Matcha tea, as well as loose tea and even lemons and cucumber for infused water. The neoprene insulation sleeve keeps my water or tea cold and makes it easy to carry or clip to a carabineer. This makes it easy to take on walks, or hiking, or even biking. You can’t go wrong with this purchase, very good quality!
