Yocan Cerum coils. One coil in this box is a green Quarts Dual Coil the other four coils in the box are black Ceramic donut coils.

I originally bought the Yocan Cerum atomizer with the quarts dual coil in the kit. I never used the quarts coil because I wanted to use the kit for wax, so I purchased this five pack ceramic coil box.
I used the my Cerum with the ceramic coils and it was amazing, but I dropped my mod and the Cerum cracked. This was a couple years ago and I was not able to find a replacement so Im selling the remaining coils. Hopefully someone out there has a Cerum and will use these coils with pride :D.

Let me know if you have any other questions.
