Micromagnets & speks

This is the final production run of 2.5mm Micromagnets and Speks — once these sell out, no more Micromagnets will be made. Every set of Speks we still have in stock is the full-size ~2.5mm variant, not the diminished ~2.35mm version the manufacturer switched to, so they mix and build consistently with our Micromagnets. And even with the natural set-to-set variation of Micromagnets, they remain higher quality and more consistent in size than Speks — see the compatibility page for the actual odds. Not sure which size you have? A chain of 40 × 2.5mm magnets should measure 10cm laid flat against a ruler or tape measure.
