Raw swordfish certificate

A Raw swordfish certificate is a certificate that is obtained by exchanging five raw swordfish with Niles at Draynor Village market, Seth at Brimhaven or Orven at Fishing Guild. Raw swordfish certificates are stackable and each one can be exchanged back for five raw swordfish by talking to Niles, Seth, or Orven.

Because raw swordfish are not stackable and players can only trade twelve items per trade screen, they are often exchanged for certificates so that they can be traded easier and faster.
