Busy builders use a hand-powered rivet tool and decorative rivets that ‘pop’ when they’re placed to complete the colourful patterns on the cards that come with the Design & Drill® Rivet Pop Café. Place a card on the activity board, load rivets into the rivet popper tool, and then press down to release into the design. Use the included rivet remover tool to pop them out, and then start on a different design. Manipulating the cards, rivet tool, and rivets builds the hand-strength, hand-eye-coordination and fine motor skills kids need to hold a fork, button their shirts, and hold a pencil to write.
