All our natural wood products are handmade from materials sourced from sustainably-managed woodlands in the UK; supporting local crafts people, woodland viability and biodiversity. These products are made from untreated wood and they will crack and change over time. This is a natural process which does not affect the use of the product and can encourage a child's investigation of the natural world.
Wood contains a natural preservative called tannin which aids its longevity. Tannin is soluble and can leach out of wood when it gets wet. Once the water evaporates, it can leave tannin sediment behind, causing staining. We recommend that you do not store your wood on a porous surface as it may cause discolouration.
