This is a 4-piece Magformers arch set from BorneLund. All pieces are genuine and stamped with "MAGFORMERS". It greatly expands the range of play when combined with basic sets, vehicle sets, creative sets, discovery boxes, etc. Please use it for supplementation as well. The product has some minor scratches and dirt from use. Please refrain from purchasing if you are particular about the condition. I am also listing other Magformers items. Thank you very much.
