This fun construction kit from Galt Toys is called Mini Octons. Inside the box you will find 75 mini octagonal pieces and an instruction book with some designs to follow.
The octons are made from tough plastic for durability and the pieces interlock easily to make a wide variety of models and designs (some to follow in the book and some to make up from your imagination). There are six colours of octon and 12 of each colour in the box.
Each octon measures 33mm x 33mm
Recommended for children aged 4+
