This little gift cost me all of $1. One set of rubber tool-shaped erasers from Dollar Tree (the pliers actually move!), and a re-purposed Home Depot gift card box that was hanging out on my wrapping paper shelf.
Dollar Tree doesn't always have the tool erasers, so you have to snap them up when you see them. Pull the inside gift card holder out of the little tool box and discard. All four tools fit perfectly inside the little box, and it's small enough to carry around in your diaper bag or purse to be used as a "busy bag" to keep your kid occupied at a store or restaurant.
Dollar Tree for the win (again!)
