First box - Strijbos

First box by Wil Strijbos.

This puzzle is a coveted sequential discovery puzzle that captivates and delights so many puzzle lovers! It is larger and heavier than it may first appear. The box is 70 mm x 70 mm x 70 mm and weighs 765 grams! It is made of an attractive blue anodized aluminum that also bears the designers signature on the front of the box. There are small holes on the sides, and one on the bottom which displays a tiny sad face when peering inside. As with all of Wil Strijbos designs, this puzzle is extremely high quality, and is a must have for any collection.

Goal: A sad face is visible in the bottom, change the sad face to a smiling face
