Review on 👃 RoyAroma 22mm Replacement Refill Pads (60PCS) - Enhance Your Aromatherapy Experience with 30mm Stainless Steel Essential Oil Diffuser Necklace Pendant Locket Car Diffuser - 12 Vibrant Colors, 6/7 Inch Diameter by Patrick Arnautov

I don't use metrics, so it was difficult to choose the right item. This item said it could be used with Tree of Life pendants, which is what I wanted them for. They're half the size I expected and while they can be used, they float in the harness. It's not that they don't deliver on what they promised, it's that they actually said they would match the followers, which worries me. It's hard when everything seems to be going according to plan and you're old enough not to understand it. I think I needed 30mm instead of this one. But how should I know? Trial and error I guess.
