Bag of Crafting is an activated item added in The Binding of Isaac: Repentance. It is available solely for Tainted Cain as his starting item.

Effects[edit | edit source]
- Upon use, pressing an attack direction will cause a swipe attack with high knockback and low damage.
- The swipe will appear further from Cain the higher his range is.
- The swipe can be used to open spiked chests without taking damage.
- Swiping any pickup on the floor will add them to the bag. The bag's contents cannot be dropped. Up to 8 pickups can be stored and if more are collected, the contents shift left and up, deleting the top left slot and adding at the bottom right. Tapping the switch key cycles the bag's contents left and up in a loop, making it possible to choose which pickup to overwrite.
- Double pickups like Double Hearts will add two copies to the bag. Blended hearts will add one red heart and one soul heart.
- Sticky nickels can't be picked up unless unstuck.
- Chests and sacks can't be picked up, but can be opened with a swipe even behind obstacles. Allows opening Mimic chests safely.
- Once 8 pickups are held in the bag, the bag will show a preview what would be crafted by holding down the Use Pill/Card button.
- Crafting an activated item while already holding one will turn the old one into pickups like collecting it would.
- If a recipe would result in an item that hasn't yet been unlocked,
Breakfast will be crafted instead.
- Curse of the Blind hides the crafting preview.
- There are a total of 26 different types of consumables that can be placed in the bag. The ordering does not matter for the outcome.
