A wonderful day playing on the beach! But what do you bring? With this product, you can 'print' mud creations. How cool! This product comes in a handy net, making cleanup after a beach day quick and easy! Instruction: Fill the sand printer up to the straight section with sand. For the best result, use dry sand. Put the lid on and fill the lid with water. Just wait! The mud drips out on its own. Start your creation! This playset is made of PLA, and these products are suitable for sensory play both indoors and outdoors. These filling molds are water-resistant and can be used very well in combination with sensory fizzing powder!
