Our building blocks are made from a variety of Nova Scotia hardwoods and softwoods. All of the blocks are unfinished so they are safe to chew. They are modular in size and pack away exactly into their own durable wooden box, which creates a puzzle for the user. The box acts as a base for building towers. Suitable for children older than a year. Contains 27 blocks in total, ranging in size from 4 cm to 12 cm.
