Buy RS3 Oyster
The oyster is an item in RuneScape 3 that may hold pearls inside. When you open an oyster, you get either an oyster pearl or an empty oyster. Most oysters that are not empty hold one pearl, but on rare occasions they can hold three. The chance of finding a pearl is about seven out of ten.
Oyster pearls are useful for Fletching. At level 41 Fletching, you can use a chisel on one oyster pearl to make six pearl bolt tips. Using a chisel on multiple pearls makes 24 pearl bolt tips at once. Pearl bolt tips are used to make gem-tipped bolts for Ranged combat.
Oysters can be caught with a big fishing net at level 16 Fishing, and each catch gives 10 Fishing experience. No bait is needed. They can also be found while panning at the Varrock Dig Site, foraged by a granite crab, or dropped by monsters like giant lobsters, mogres, rock crabs, and mudskippers.
The oyster is a light item at 0.1 kg. It can also be disassembled for Invention, giving simple parts most of the time and variable components on rare occasions.
