Using these Tinker Rings is easy! You can simply stack them up from the biggest to the smallest. The magnets inside will make them snap together no matter which side of the rings is facing up. For more fun, try hanging the rings from each other. To keep your Tinker Rings in good shape, avoid exposing them to sharp objects that could damage the soft rubbery surface. You can clean them with a mild soap and water. Just make sure to dry them thoroughly before storing. Keep them out of reach of small children under 2 years old as small parts could be a choking hazard.
