What do you get when you combine Karim Rashid and 3M? You get the Pebble Collection that features a Post-it dispenser and Scotch tape dispenser. The pieces are supposed to resemble pebbles and comes in white, black and purple. Both pieces feature non-slip bottoms and are weighted so that they stay in place and can be used with one hand without them moving. The top of the Post-It Dispenser twists off so you can refill it with additional Pop-Up Post-It Notes.
