Aromatherapy Snaps!! Simply add your favorite scent right to the clay, then switch snaps later the same day if you want a new scent! NEW and ONLY Available Here! Snaps right to any 18mm piece of Snap Jewelry. l Love mine I wear it all the time! ( snap02 ) Snap size :23mm Snaps to ANY Ginger Snap 18mm Piece of Jewelry. Add essential oil to the Aromatherapy Snap and it soaks in and becomes your diffuser. This is a wonderful was to enjoy your favorite scents! The scent will fade away over the next day or two depending on the oil you use. For example lemon wont last as long as peppermint which is a stronger scent. Once the scent fades away simply reapply different oils as needed. You will find that some scents blend nicely with each other so that applying a second oil on top of the first works great. For the strongest scent add one drop each day. Make sure the oil has soaked in before putting it next to clothing. The polymer clay is durable and water resistant. Please note: do not use straight Lemongrass essential oil on Clay Charm, blends with Lemongrass are fine to use. Please Note: use caution when unsnapping the Aroma snap and make sure you are pulling from the edge of the snap itself and not the clay. Aromatherapy Snaps are made exclusively by me here in my kitchen in the mountains of New Mexico.
