Circuit Blox™ - 6선 블록 - E-Blox®

Bought this to replace a wire block that got lost, and the connection clicks in just as snugly as the originals. It's one small piece, but it's the exact 6-wire link my son needed to finish his circuit.

My kid's build kept dying halfway because he only had one wire block in his set, so adding this 6 wire block fixed it right away. The connection clicks in solid and the pieces fit the same as the originals.

Picked up this extra wire block after our first set came up one short for a longer layout, and it clicks in just as snugly as the originals. Being able to buy the single piece instead of a whole new kit saved me a bunch. Now the whole circuit actually stays connected.
