Snapperz

From the website:

Snapperz is a simple fidget toy that will suck you in... literally.

The silicone square contains two suction cups that oppose each other.

Give it a squeeze and they'll stick together.

Release your grip, and they'll pop apart, making a superb snapping sound.

The delightfully simple toy can be popped again and again as you find yourself lured in by the siren call of the satisfying snap.

2.25" x 2.25" x 0.75".

Note: Because we receive this item in an assortment of colors, we must sell them randomly. You'll receive purple, light blue, royal blue, magenta, lime, or orange.
