I have had a lot of people wondering about Primark charms on the blog.
These are a couple which I have, cherries, a skull and the initial 'M'.
Primark sell both bracelets and necklaces for their charms. The photo above is of the necklace although I am wearing it as a bracelet. All the charms and the necklace / bracelets are currently £1. So far none of mine have tarnished but for £1 I imagine they will.
I have been using the charms on things other than with the chains they have, they hook on to anything really as the clasp is one of those like a normal necklace, you can see it in the photo attached to the 'M'. Often have a charm clipped on to a black elastic choker type thing, or hooked on to a zip on a bag.
