Connetix 42-Piece Rainbow Square Expansion Pack

The Connetix 42-Piece Rainbow Square Pack is an expansion set featuring 6 large and 36 small magnetic squares in full rainbow colors. Connetix tiles use a distinctive beveled design that creates clear light refractions while maintaining strong magnet seals. The set is made from non-toxic ABS plastic (BPA and phthalate-free), ultrasonically sealed and riveted for safety—meeting standards suitable for ages 3+.

This is a pure expansion pack, not a standalone starter set. It pairs with existing Connetix collections or other leading magnetic tile brands to expand build possibilities. The beveled aesthetic and magnet strength earn consistent praise in parenting forums and r/Magnatiles communities. However, at ~$1.55 per piece, it sits in the premium tier—roughly double the cost-per-piece of value clones but justified by durability and magnet performance. Best suited for families already invested in magnetic tiles seeking to build bigger, taller structures with additional color variety.
