Black plastic flexible and compatible detailed linked treads (x2). Unknown from what toy? Plastic links are tank or tractor treads pair, molded, approximately 1.5" W x 9.5" L folded flat Like-NEW. Someone could make a great toy out of these treads!! Highly detailed and professionally produced with flexible handling, these two unbranded plastic treads are linked and belonged to some child's toy before being separated?! Great for building homemade toy tractors or tanks. See photographs for condition and overall appearance. US/Canada domestic shipping only, no international sales.
