The Wooden Toy Co Building Blocks 25 Piece Set Large is a great toy for kids. These kids building blocks are open-ended and very beneficial for learning and development. These natural wooden blocks are made from certified, sustainably grown Victorian Ash hardwood, grown right here in Victoria. They have a fantastic natural colour and feel. They have a smooth texture and the natural oils allow for a premium finish, while still grippy for little hands. All of our toys are made in Melbourne, Australia. Dimensions: Our wooden blocks are 42mm wide and range in height from 126mm to 210mm.
