One of the particular requirements of this Rozy wallet is the closure. You will need a special clasp.
So, you ask, where can you resource those?
I found some stores and when I find more, I will mention them here.
They all ship internationally.
In the US you van buy it in the shop from Cari, The Wooden Seamstress.At the moment she sold everything, but I’m sure she will have new supplies.
Vickey from So you need hardware has a special selection in her bigcartelshop : http://www.soyouneedhardware.bigcartel.com/product/7-1-2-bar-clasp
