They are everything I was looking for: clear so I could enjoy the hues, double-walled so I don't have to worry about where I sit it or heat while holding, and are quite lightweight for comfort. In the 6 months I've been using them, they've proven sturdy enough to still look brand new. They were packaged well and arrived in perfect condition.
The insulation and lightweight borosilicate make these a joy to use daily.
I absolutely adore these glass mugs. They are just beautifully elegant, while also supremely practical. The borosilicate makes them incredibly light, so despite the insulating double-walls, they are extremely comfortable to use, even with arthritic hands and wrists. I definitely recommend them.
The first thing I noticed was how freaking light these mugs are - they're about 1/4 the weight of my normal mugs for tea. They definitely keep the tea warm while not conducting heat too much to your hand making it easier to sip and enjoy very warm tea. They're functional, dishwasher safe, and look cool when they're full of tea! Very comfortable to hold as well.
