I see a lot of clothing design on your Instagram, where can I buy them?

Most of the clothing & apparel designs are currently in sampling stage. I am working hard with manufacturers to make them perfect. Preorders will open soon once the products are ready!

What is the difference between A-grade, B-grade and C-grade enamel pins?
Can I change the address for my order?
I am from the UK, how can I place an order?
How long will it take preorder items to ship?
Will I receive tracking number for my package?
