Description

One shape, thirty-three times

There is no mix here, just one part in quantity: the square 2 x 2 brick in black. It is sturdy, fits into corners and walls, and works well for towers, pillars or compact walls. Anyone short of them in a basic box could top up with this pack. The uniform colour looks calm and combines easily with brighter bricks.

Where it fits today

The set is a textbook example of the supplemental packs from the early System years, and for collectors a gap that is easy to close. In a build it serves as a stock for foundations and walls. This page shows the full parts list, and the What Can I Build tool reveals which models the pack and your own bricks could make together.
