Kinnikuman Mask Kinnikuman mask. This is a deadstock item from the time it was made. Instant purchase is welcome. I don't relist items very often. I have over 200-300 items for sale. I may have other military items, nostalgic items, and rare finds hidden away, so please take a look at my other listings if you have time. You might find something unexpected that you've been looking for. I don't know if you will find anything though...
