Kinetic cups keep fidgety fingers busy while relaxing with a tasty adult beverage. They're also terrific for any kind of drinks. The bottom is trimmed with a rounded surface so it is easy to spin, rock, and just fidget in general. The thumb dent is a nice spot for your digits to nestle but is also another kinetic spot attracting the desire to fiddle with it between sips. As a person who peels the labels off bottles and plays with straw wrappers, this was a natural design for those fidgety moments. I occasionally refer to it as an adult fidget spinner.
Every element was intentionally designed to function well. The lip is thin enough it doesn't dribble but thick enough it doesn't chip easily. The bottom has added weight to keep it upright as you play with it. Each one is thrown by hand on the potters wheel so they each have their own unique characteristics making them unique even though you can also put together a set. They make a wonderful gift for dad or a hostess gift!
