We love that it's sustainably made in Thailand using chemical-free rubberwood, formaldehyde-free glue, organic pigments and water-based dyes. With a strong mission to create a sustainable world, Plan Toys intentionally considers every single step of production in order to minimize environmental impact. This mission is implemented through the three pillars of Plan Toys business, also known as our “Sustainable Way.” This includes Sustainable Material, Sustainable Manufacturing and Sustainable Mind.
