10 x 8mm dentelles in Backlit Tequila (Vintage Czech)

This is a pack of 10 vintage dentelles with a foiled backing. They are similar to chatons, they have have a faceted top but the point on the back has been replaced with a flat section. They are about 8mm in diameter and are similar in colour to the modern Backlit Tequila. Due to their age, some of them have marks on the backs but this can't be seen on front.
