Many Geomag sets with balls and rods also have special panels to fill the gaps between the rods. These panels make the final craft look more solid, adding surfaces to the empty construction. There are many Geomag sets with these panels of different shapes and colors. This classic panel set with 200 pieces is the biggest of its type. This set is orange and red, while smaller sets of this type, for some reason, come in green and blue. The set includes triangle, square and pentagon panels, along with balls and rods to build from.
