Navaris Sauna Aromatherapy Stone Cup - Ø 5cm Heat-Resistant Home Sauna Accessories Stone Cup Essential Oil Holder - Durable Soapstone Essential Oils Scents Diffuser

We use this in our barrel sauna to melt menthol crystals and it works great!

Simple effective product

Be aware of the size, it’s very tiny .

The product overall is fine. What surprised me the most was the SIZE. It's tiny. I was thinking it was going to be more like the size of a tennis ball vs. a larger marble. Besides that it's fine.

Product seems to be functioning properly as of now. The packaging it came in was horrible

It works and is all that it needs to be. For some reason I was expecting something more along the size of a baseball, but it’s the size of a shot glass. It’s cute and I prefer it this small, handling oils- doesn’t need much space. Nice stainless steel thimble inside a little stone coozy. I rest it above my sauna stones and love the aroma therapy infusion.

These are slightly smaller than a shot glass. Really nicely made.

Definitely doesn’t work no smell i am putting the oil directly in the water for the rocks
