Produced by a special needle, this magic tattoo is comprised of multiple hooks that serve both aesthetic and functional purpose.

In a small township, there lived a talented seamstress with the ability to imbue a modicum of magic into the bags and clothing that she tailored. One day, after finishing a request for a bag with an interior far larger than it would appear to have from the outside, her patron refused to pay, knocking her to the ground and running off with the item clutched tightly in his arms. This incident affected the seamstress deeply, and she was never able to recreate the same item again due to the lingering trauma. Her partner, a tattooist, was able to replicate a similar effect within one of his designs years later, which did little to help the seamstress move on from her troubling memory, but contributed greatly to the global need for more portable storage solutions.
