Review on Kavako Coffee Reusable Stainless Filter: Elevate Your Brewing Experience by Russ Charmin

perfect for drinking tea! I hate to use the term "perfect" but they are perfect for my purpose - a good glass of tea in the microwave! There were so many concerns when I chose this set of borosilicate teacups! I needed a fairly strong glass, which is unrealistic as all glasses are breakable for this purpose----and the point of whether it's lime glass, borosilicate glass, double walled or anything else! The difference is that borosilicate glass is shatterproof and less prone to fogging! I like the design and the size best! it was exactly 10 ounces and pretty flimsy! but like I said, I really don't think it matters as most glasses are brittle ----- period! While it would be nice if the jars looked like lab borosilicate or pyrex, I think the problem would be the physics, cost and weight of lifting a full jar! Having said that I would highly recommend these glasses as I know they are much safer than drinking from traditional cups due to the lead and cadmium getting into your tea on the surface!
