Circuit Blox™ - 2線塊 - E-Blox®

My son's circuit set was missing this exact piece, and this two-wire block snaps right in with no issues. It's sturdy and does exactly what it's supposed to for his projects.

Our set was one two-wire block short, so this little piece saved the whole build. It clicks in flush with the other blocks and the wires line up without any fiddling. My kids rebuilt their light circuit in minutes.

Ordered this as a spare since we keep building bigger circuits and always seem to run short on two-wire blocks. It snaps in just as firmly as the ones from the original set, no loose connections. Now the kids can finish a build without stealing a block from another project.
