1Spark 3-in-1 Glass Tumbler

The average person opens their Tumblers 18 times a day.
Ok, we made that up. Either way, it gets tedious.

With Onederful - you get an innovative and, may we add, super cool, 3-in-1 lid with a hidden straw to drink till the brink. Hand-crafted borosilicate glass lets you enjoy hot or cold drinks at extreme temperatures, and a stylish insulating sleeve provides a comfortable grip.

Go ahead and enjoy the ultimate drinking experience from a reusable cup.
