Boston crystal prismatic badge.
This is an unusual type of badge, it is a metal badge with a resin top and a prismatic effect design. They have been in storage for many years, but are brand new and have never been used, although occasionally the resin has become a little scratched.
size: 1" / 2.5cm
These were made in the eighties, so are now very collectable.
Ideal to pin onto any item of clothing.
