Love cowrie shells so much, such a tropical feel to them!
As a child I used to spend hours on the beach trying to find them... which I now do again with my daughter! They remind me of happy days!
Cowries are around 9mm long. Hoops are around 2.5cm wide, made from a lead and nickel free metal alloy. Try not to get the hoops wet as they might tarnish. Also keep them away from moisturisers etc. xx
