Thank you for viewing! Yokomo Koonies Chaser Kai Weld Mark II Specifications. This is a body from Sanei Shobo Welk, released about 17 years ago, with the "Hyakushiki" Mark II decals. Back then, there were no 100 Mark bodies available, so this is a decal set to convert to a 100 Mark. It has been stored in a closet for many years. Although it has deteriorated slightly, I think it can still be used. I will sell it because I no longer use it. Thank you.
