Review on Bamboo Double Wall Borosilicate Coffee Tea Cup by Frank Webster

Nice design, good quality. Extremely lightweight borosilicate glass with bamboo stopper with clear plastic spacer. (Ours was NOT emblazoned with the Starbucks logo. Thanks for that.) The lid and light weight are most important for our purposes, since we bought it so that a person with a weakened left side who walks with a cane can use theirs You can carry coffee - with your left hand - from room to room without spilling. The lid closes easily and doesn't require screwing or precise alignment like many coffee mug lids, which can be difficult for someone with limited one-handed mobility. And it serves as a fairly attractive stand. It also doesn't require the person to drink through any of the many slots, bars, sliders, or spouts found on travel mugs. It works like a regular old coffee mug that you drink from like any other coffee mug. And while this may not sound like much, it can make a world of difference for some stroke victims. Thumbs as they were meant for "drinking" and didn't spill out when worn. Problems with water ingress between layers. Very good product. We are very satisfied.
