The X may seem elusive but they can be found and come around, Those listings are resellers that sell Mercari items on ebay, they don’t even own those items. If you are interested in them go to the source. Mowl however warns about these resellers and also limits buyers to single pieces so they can’t resell at these higher mark ups. I haven’t played the new version of X yet without spacers, but hopefully @mowl will make this design more available.
