Marie-Paule from So Popo Sew gave me this great hint: she ordered 50 invisible zippers (40cm) for only 19,99 dollar on the Aliexpress website! What a bargain. So I order my pack as well and only two weeks later my zippers arrived. I’m very happy with the colourful mailbox surprise. Thanks again Marie-Paule!
And guess what: the shop owner is giving away an extra set of zippers to one of you! Just participate below. If you can’t wait for a colourful pack to arrive, you can also just order the zippers HERE. I can surely recommend their service.
