As a tester, you could either receive a single nub to test for free, or pay shipping to receive a trio of nubs. I opted for the latter, and received a pack of nubs in magenta, cyan, and yellow - like printer cartridge colors!

The nubs were easy to attach to the tile -- just clean off the area you want to stick them to, and peel and stick. They were re-positionable, as I ended up needing to switch the cyan and yellow nubs. The game could be used by a toddler to sort by color or shape, and by a pre-schooler to put the numbers for each color group in order. Everybody will have fun sticking the foam shapes to the bathtub walls.
The Puj Nub is primarily designed for use with the Puj Hug -- a towel that has a rubber fitting that hangs on the nub when not in use, and loops with another rubber piece to wrap around your neck for when you take baby out of the bath. I am excited to see the creative uses other testers come up with for this fun new product!
**As mentioned, I paid for shipping for the nubs, but am testing them on behalf of Puj. Opinions expressed here are my own.
