Every mom knows how hard it is to get kids to pick up after themselves. But with Puj Nubs, picking up is fun and colorful. These bright colorful hooks have a grippy, soft tip, which makes it fun and easy to hang household accessories. Because they are made from a soft material, they are safe and fun for children too. They are also very easy to use – simply peel off the back and stick. They are created to be used on the smooth surfaces like glass, metal, tile, and shower walls.
