I am very sorry but I don’t ship beyond the USA because I am a one-man operation who has little knowledge of VAT, customs forms, or international shipping rules.
In addition, the shipping cost would far exceed the price of the chain.
To make amends, I found these instructional videos to make your own.
You’ll need 30 split key rings from a craft store or hardware store . . .

Or you can use 30 binder rings from an office supply store . . .

You can use any size diameter but 30 to 40 mm is good for personal use.
I hope this helps. Please write with any questions.
