This is not a collaboration product with minä perhonen. It is a handmade item using minä perhonen fabric. I made a very small triangular pouch using scraps of minä perhonen fabric and half-linen fabric. It's small enough to attach to a bag as a key holder. It can hold coins, accessories, medicine, etc. Zipper: Approximately 6.5 cm Widest side: Approximately 8.5 cm Height: Approximately 6.5 cm As this is a handmade item, there may be slight stitching errors.
