This is a dark gray urethane foam insert for Greenmax small vehicle cases, capable of storing two 20m-class vehicles. I am selling this because I replaced the urethane with a different one for storing three vehicles. *Shipping will be via Yu-Yu Mercari Bin (Yu-Packet Post), but I can accommodate other shipping methods upon request. Please inquire in the comments section. *I have two other types/colors of urethane foam inserts available. If you purchase multiple, the second item and beyond will be 130 yen each. [Priority will be given to those who purchase immediately, not those who comment first.]
