Sleeves of StorageBackpack 4

Price 100 gp
Weight light
This loose robe has wide, voluminous sleeves that each contain an extradimensional space. These spaces each function as a Bag of Holding that can hold up to 5 Bulk of items (for a total of 10 Bulk), though no individual item can be of more than 1 Bulk; the sleeves grow slightly heavy as you reach maximum capacity. You can add or remove an item from a sleeve with a single hand free as an Interact action.
If a sleeve is completely empty, you can place your own familiar into that extradimensional space. It can survive comfortably in your sleeve for up to 1 hour, after which it begins to suffocate. While in your sleeve, it can't be affected or targeted by any effects, but you don't benefit from any master abilities. A familiar can exit the sleeve of its own volition with a single action that has the manipulate and move traits. You can't place any other creature into your sleeves, nor can you place your familiar in a sleeve if it's larger than Tiny. If your familiar is in your sleeve, you can't place any items in the sleeve.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ConjurationEffects and magic items with this trait are associated with the conjuration school of magic, typically involving summoning, creation, teleportation, or moving things from place to place.
ExtradimensionalThis effect or item creates an extradimensional space. An extradimensional effect placed inside another extradimensional space ceases to function until it is removed.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
