40-piece Explorer Natural (magnetic wood blocks) from Tegu Blocks. 

Reach new heights. Approach your tall tower from all kinds of new angles! Tegu angle blocks allow geometric building possibilities for gravity-defying play that takes you to the edge.

The Explorer Set includes 40 magnetic wooden blocks in seven shapes: 4 Large Columns, 8 Mega Planks, 8 Long Planks, 4 Medium Columns, 4 Small Trapezoids, 4 Large Trapezoids and 8 Short Planks. Tegu blocks come packaged in a beautifully designed box large and rigid enough to store the blocks for many years to come. Also, don't miss out on some really fun factoids about the blocks and their origin on the inside of each package. Each set also includes The Tegu Story -- a booklet containing various building ideas and information about Tegu's social and environmental initiatives.
