We are passionate about UK grown wood supporting the future of our woodlands and providing natural alternatives to plastic play and learning resources. Natural wood is a fascinating material unlike a sterile plastic item. Wood changes, its bark comes away, there will be knots and small cracks which will expand and contract as the wood changes over time. This all is amazing and it stimulates questions and helps connect us to the natural world.
The product has not been treated with a preservative although 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 will leave tannin sediment behind, causing staining. We recommend that you do not store your wood on a porous surface as the surface may discolour.
