Circuit Blox™ - Magnet - E-Blox®

I needed a spare magnet for my building set and this

Snapped right into the empty slot on my kid's circuit board and the light lit up first try. The magnet holds tight too, no wobble when he's swapping pieces around. Nice to know I can just grab a single piece instead of buying a whole new set.

Lost one of these little magnets and my circuit build wouldn't light up anymore, so this replacement saved the whole set. Snaps in firmly and holds the connection just like the original piece did.
