Â
Due to new tax and customs regulations we are temporarily unable to deliver goods ordered at Blazko WebShop to United Kingdom after 20th Dec.
Â
We hope to be able to deliver to You again soon, after the chaotic transition process is finally over and all the rules became clear.

We use Polish Ring Size system stated in the chart below. It starts with size 1 at 12.666 millimeters and increases in increments of 1/3 millimeter.Â
To check your ring size you may ask your local jeweler for help and professional measure. At home You can try to measure the inside diameter of a ring that You already have using a caliper - we'll need exact diameter in millimeters.
You can also visit internet sites (eg. International Ring Size Convertion Chart), where you can find some easy ways to measure your ring size - not so accurate though. If You have any questions or need help choosing your ring please email us: sklep@blazko.pl
