This colorful jewelry is made with bits and pieces of old vintage tins. Biscuits, candy and tea were often packaged in pretty in containers. Consumers would then save the tin as useful storage and home decor. Lucky for us some people held onto these tins for a very long time. Tins can date back to the late 1800's. Hightly sought after if marked "Made in Engleand" or Made in Holland" No worries. I only use tins that are damaged or otherwise unwanted.
