The starter and these shop pickaxes are unbreakable. Review the item and total, confirm the purchase, then use the shop mailbox to collect it. A higher mine rank does not give a shop tool for free.
Backpack
Open /backpack or the Backpack guide button. Storage grows to 1 row at A, 2 at C, 3 at E, 4 at G, 5 at I and 6 at J. Move items yourself: automatic overflow collection is off. Prestige keeps unlocked rows and stored items.
Prison Trading
Player listings use Gems and remain within Prison. Review the item, total price, fees and expiry. Collect purchases and returns through the market. Sell Inventory does not sell backpack contents or tools.
