This is a 36-piece set of Magformers curve pieces from BorneLund. The product composition is as follows: Sector 8, Arch 4, Sector (Large) 9, Arch (Large) 4, Quarter Cone 4, Eighth Sphere 1, Half Arch 2, Circle 1 All pieces are genuine and have the "MAGFORMERS" stamp. The range of play expands greatly when combined with basic sets, vehicle sets, creative sets, discovery boxes, etc. Please use them for supplementation as well. Half arches and circles can be used to create works like those in images 9-11. 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.
