Springcreek USA (100 Pad Value Pack) Aromatherapy Essential Oil Diffuser Locket Necklace Refill Pads, Car Vent Diffuser Pads, 7/8" (22mm) Diameter, 20 Assorted Colors

Very happy with this product, i had to trim the pads very slighlty to ge tthem to fit my diffuser necklace, and I am using 2 pads in it instead of one. they are thinner pads than i am used to getting, but for the price, I can deal with trimming the outer edges of the pads and using 2 pads in with each new oil I use. Definitely worth it for the money. Shipped fast, would buy them again when i need more - and I should mention, my package had 25 extra pads in it. :)

I use these pads in my diffuser necklace and in my car diffuser. I love all the different colors. There's one to go with just about every outfit. They're the perfect size and fit well

What a nice bargain. I just bought a diffuser necklace for my daughter, me and a friend. These refill pads are great. They are a bit larger than my locket, but no worries, I trim it down to size. Will check next time to see if they make the 3/4". But would definitely recommend these for sure!

Said it would fit 30mm size aromatherapy necklaces...these are actually smaller than my 30mm size pad that came with the necklace. Unsure of why, if not for that it would have been 5 stars.

Bought necklaces for my daughter and I so we share these discs for the essential oils

I have two diffuser necklaces. These only fit in one of them.

Keeps the scent for a long time!

Good deal
