サーキットブロックス™ - ワンブロックスペーサー - E-Blox®

Ordered this single spacer to finish a build that was one block short, and it clicked in perfectly with the rest of the set. Same solid fit as the pieces that came in the original kit.

My son's build kept collapsing until we realized the spacer had gone missing, so this single replacement block saved the whole project. It clicks in just as snug as the originals that came with the set.

Lost one of these spacers under the couch and the whole tower stopped lighting up, so I grabbed a single replacement instead of buying a whole new set. It clicks in just like the originals and the circuit works fine again.
