Lilipan Vest, what do I do with this item?

Found a lilipan vest and wanted to know if I can exchange it for clothes or something. Can someone help.

Used as trading mat for skill rings obtained from ring shop the Cafe area.

@flyjediguy You trade them to the NPC Yerkes (the old man butler) in Franca's Cafe for 100,000 meseta each week.

@flyjediguy You can meet a NPC Yerkes at Franca's Café, take his client order "Procure Lillipan Vest" to exchange the item for 100,000 Meseta. This client order can be accepted once a week for every characters you have.

EDIT: ninja'd!
