I have deisgned these hoops so you can wear them with multiple charms. You can choose from the small (2cm diameter) or large (2.5cm diameter) pair of hoops and then you have the choice of charms to add if you would like to. 
 
Charms:
Hearts
Seafoam Seaglass
Silver Circles 
9ct Gold Circles 
 
The charms slide on over the post and wont fall off the other end due to it's flattened nature.
 
Please note the seaglass charms are one offs and I will try to remove them as an option when they have been bought. I will also try to upload more seaglass options when I have made some!
