On September 26, 2011, Roblox announced a building toy block set. Each block was a one-inch wood square with decals on two sides. On one side were the letters of the ROBLOX logo, and on the other side, there were some classic noobs. Each set cost $12 USD - shipping and handling included. It was for ages five and up.
There are a few rare sets of these block sets that were signed by the Roblox staff. The first ten orders received a unique set of these blocks.
