Trendglas JENA
Costa II Glass Mugs set of 6
$75
Six glass mugs, 8.5 oz each, made from Trendglas Jena borosilicate 3.3. They serve coffee and tea equally well, and clear glass has the quiet advantage of showing you exactly how strong the cup is before you drink it. Borosilicate 3.3 is certified allergy-free and pore-free. Pore-free is the practical part: nothing soaks into the surface, so a mug that held coffee this morning is a clean mug for tea this afternoon, and the glass does not stain or hold a smell over time. A set of six is a conference room quantity as much as a kitchen one. Each mug is 4.1 in tall, 3.9 in wide and 2.6 in deep, and they are microwave safe, dishwasher safe and heat resistant.
