Circuit Blox™ - قطعة سلك واحدة - E-Blox®

The transparent blue makes it easy to see the wire path, and it clicks in securely with my other blocks. Exactly what I needed.

The transparent blue color makes it easy to spot which block is the wire when I'm digging through the bin. Only reason it's not five stars is I wish it came in a multi-pack, since one block alone rarely solves a build. Works fine as a replacement though.

Snapped right into my existing set and the blue tint matches the rest of my blocks perfectly. Only gripe is that there's no marking on it, so if you mix it into a big pile it's a bit of a hunt to find. Does the job for a spare wire though.
