You can keep Orbeez fresh for longer by adding a pinch of salt when growing them. You can play with your Orbeez several times before needing to replace them.
Like any water-based product they will need to be replaced with fresh Orbeez if you smell or see any mold. Orbeez in the Light- up products will last several months with no problems if not exposed to air.
