20 Yellow Square K'nex Panels with Rectangular Hole and 12 Inserts - Blue, Pink, and Yellow
Approximately 2.5" wide, 3.44" diagonal. These panels match the size of the standard 3-7/16" yellow rods along their diagonal and the 2.25" blue rods along their side. Also included are 12 inserts that snap into the rectangular opening in the panel - 4 each of blue, yellow, and pink/fuchsia.
These pieces are brand new, unused although they may show some light scuff marks from rubbing against other pieces while packed in a loose bag.
