Pretty as a glass sturdy as a rubber.
It is more practical to use plastic cups on picnics and outdoor parties because of its durability. However, the trouble is that most of them are ugly but not the Snow Peak silicone cup. Because it looks exactly like glass. Made of silicone, this cup can be tossed in your backpack safely. It is clear and smooth like glass but when you hold it, it’s flexible and unbreakable. It won’t break because it just bends. Highly recommended for camping dates and classy backyard parties.
