This is a set of 8 isosceles triangle pieces from Magformers by BorneLund. These are genuine products, with the "MAGFORMERS" imprint on all pieces. They can be combined with Basic Sets, Creative Sets, Vehicle Sets, Discovery Boxes, etc., to expand the ways you can play. They are also useful for supplementing your existing sets. The product condition is generally good, with some minor scratches and dirt from use. However, please refrain from purchasing if you are particularly concerned about the condition. I am also listing other Magformers items. Thank you for your interest.
