These essential oil diffuser pendants have side hinges and space for a felt pad inside. I have Batman, Superman, Wonder Woman, and Captain America!! These are made of heavy duty stainless steel and are well made.
All pendants come with three felt discs. Silver pendants come with a basic ball chain.
20 mm are the size of the top of an EO bottle
25 mm are the size of a quarter
