These fun PLA building blocks are suitable for sensory play both indoors and outdoors. These building blocks are water-resistant and can be used very well in combination with mud, for example! Build the wall and create with imagination. PLA is a biodegradable material, produced from plant-based resources such as corn starch or sugarcane. A sustainable alternative to traditional plastics! Combine these building blocks with our construction vehicles or play sand and one of our other fun accessories, and the play tray is completely complete! Dimensions: 3.1cm x 1.5cm x 1.1cm
