Finding hardware and zippers for bag makings can be a journey. In the US and Canada, you can find more then one. For Europe, it’s a whole other ordeal. Importing from the US or Canada is just not affordable. not only shipping cost is high but also customs make it extreme expensive.
Lucky for me I discovered Aliexpress from the beginning of my bag making adventure.
I can find almost anything in China. 99% of it is free shipping.
Why would I pay 2 euro for 1 piece, if I can get 50 pieces for 4 euro?
