Sublimation glass beer mugs are made of durable borosilicate glass, Lead-free and BPA-free, lid is made of safe plastic that with a silicone ring prevents splashes, much easier to clean than bamboo, won’t get moldy, which endure the fast swings in temperature between -68F° and 212F° (-20℃-100℃), and with a ergonomic handle, so you can easily hold the cup, not easy to slip from the hand, and take it anywhere.
