This is an essential oil diffuser pendant with a side hinge and space for a felt pad inside. The front has a mouse design, with cut-outs so the scent of your oil comes through. It's made of heavy duty stainless steel and is well made.
All pendants come with three felt discs and with a matching basic ball chain.
20 mm are the size of the top of an EO bottle
25 mm are the size of a quarter
