I mean this mask:

Which is named "Genshou Mask: White/Black" (Depending on the color), however, player shop for some reason refuses to show those, it keeps saying "Item not found" appearently.

When you searched, did you type the name in the item field (whether complete or partial), then hit the "Search" button right next to it that brings up the "Candidate List," or did you type out the exact name of the item and then hit "Search by Price" at the bottom?

If the former, it more than likely means that their names have been pushed out of your Item Name Cache, and you have to search using the latter method.

If it is happening when doing the latter, then it means that no one has them in their shops.

the item name you are looking for in game is called Genga Mask
