New model wide-neck glass non spill straw cups now come with a patented silicone sleeve with built in shock absorbers that help to prevent breakage when dropped. In fact our drop tests (from up to 8 meters or 3 storeys high, with no breakage) have us suspect we have the most drop resistant glass straw cups known to planet Earth!
The non spill glass straw cup is made from highest quality tempered thermal shock resistant borosilicate glass (commonly used in science labs) allowing bottles to transition safely from freezer to boiled water. The protective medical grade silicone sleeve not only provides super shock resistance; it changes colour if the liquid inside is too hot to serve to baby!
