 SCP-226 is a cardboard box, measuring roughly 30 cm by 20 cm by 4 cm. It has a lid that fits securely over the bottom half, as with any common puzzle box. The surface of the box is a deep black, with the word fear, scrawled with white ink on the upper right corner of its lid. Within the box are 1000 cardboard puzzle pieces, each measuring roughly 2 cm in diameter, also considered SCP-226. When completed, the puzzle always forms in a rectangular shape. However, the design and order in which the pieces fit together change with use. SCP-226 aligns itself with whoever initially opens the box. When opened, the pieces change design, and the completed image will show what has been discovered to be the greatest fear of the person who it is aligned to. The image on the pieces do not change after the box has been opened.
