Bond

A bond is an in-game item that allows a player to pay for selected account-related and out-of-game benefits such as membership, Runecoins and Spins with in-game resources.

Tradeable bonds may be traded to other players and sold on the Grand Exchange; however, when the transaction is complete, the bond will become untradeable. A bond is always bound to a player when it has not been redeemed or traded to another player. It is always kept on death, even when inside the wilderness.

Uses
When bought using real life currency, bonds are tradeable. Once traded to another player for an in-game sum of money or items they become untradeable. Bonds can be made tradeable again for a payment of 10% of their Grand Exchange value (currently at coins). At any time, whether tradeable or untradeable, bonds can be redeemed for one of the following:
 * 14 days of membership
 * 8 Squeal of Fortune spins
 * 160 RuneCoins

Price per unit
The below prices are subject to change, depending on a bond's Grand Exchange value:
