Dig it out kits are a great way for kids to learn while having fun and making a mess. Each kit comes with everything you need to find the treasure inside. The block is made from gypsum and plaster so is safe for kids to dig in and the brush and tool are made from wood. There are assorted designs to collect and discover. The kit is recommended for children over the age of 3 due to the small parts and we recommend that children are supervised while digging the items out. Have fun!
