Raw lobster certificate

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

Because raw lobsters 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.
