If you have a Kirigami set, you need to buy these inserts. I use the large as a clutch and the smaller ones as catch alls or card holders, but with the inserts I can use all three as crossbody bags, even the tiny ones make such cute mini bags. The chain looks delicate, but it has a nice weight to it and is such great quality. I’m 5’9 and ordered the large chain and it hits in the perfect spot.
