Pin Pres can be adapted easily since the surface is made of lots of sliding "pins." Pull out a few adjacent ones to create a shelf, or stick any toy into extended pins to produce a custom-sized, cave-like compartment. Or, if cleaning up isn't your game, press your whole body into the board to leave an impression.
It's a fun concept, although perhaps more toy than shelf. With pins extending on both sides, you'll need to place it somewhere where you can access both sides. But we find the concept fantastically unusual and innovative. The product doesn't appear to be for sale in OOO My Design's shop yet, but we hope to see it there in the near future!
