The Play Coalition 'Cliff Hanger Mug' Improves Your Grip Strength

First of all, a word of warning: unless you are a professional, do not fill the Play Coalition ‘Cliff Hanger Mug’ with scorching hot coffee. The lighthearted design of this porcelain mug takes on the conventional form and size, except the designer has nixed the usual handle for a indoor climbing wall hold.

Bolted firmly to the Play Coalition ‘Cliff Hanger Mug,’ the crimp holds test and promote your grip strength, enabling you only to use the tips of your fingers to pick up the cup. Apologies for the rock-climbing pun, but this is one "jug" you’ll have a hard time holding on to.
