The Snail Puzzle is great for teaching zoology or just for use as a fun activity for toddlers and elementary-level children.  It measures 24 cm x 24 cm (about 9.5 in x 9.5 in) and is made of durable, warp-resistant plywood with a satin-touch, natural wood finish.  Each puzzle piece is fitted with a wooden knob for easy removal, and the image is silk-screened directly onto the wood and then covered with a clearcoat to protect it for years to come.  Weighing about 400 g (just under 1 lb), the puzzle has a pleasant weight to it, and fits into either of our puzzle cabinets for easy storage.
