Price listed is for ten charms/settings. These are brass flower shaped charms that measure approximately 13mm by 10mm wide. This measurement includes the loop at the top. There are ten settings for 15pp point back stones (or 2mm round back no hole beads or pearls) and one 24pp setting in the center. You can see that these do not have prongs. Stones will need to be glued in. You could use stones or beads that are slightly smaller/larger than what is listed.
