"Insets" are also called the smallest blazko cells :) Tiny squares 6x6 mm. and 0,7 gr. weight are made of silver, acrylic and copper dot in the middle of each colour field and are the most classic and minimalistic example of my whole Chess collection.
Available also in other colour versions on order.
If you choose ”Other” as a colour option please write a comment while ordering and let me know which colours should I use.
