Bags of Transference - Very Rare (DI)

A pair of burlap bags that are approx. 9in. deep x 6in. wide x 1in. thick & can hold a maximum of 3 lbs. each. Items placed in the bags must fit completely to be transferred. As a bonus action, a creature that knows the command word can speak it, causing each bag's contents to switch to the other bag. There is no range limit to this feature though both bags must be on the same plane of existence.

Uncommon - 1/day transference, bags & contents are detectable by magic
Rare - 1/day transference, bags & contents are not detectable by magic
Very Rare - unlimited transference, bags & contents are not detectable by magic
