The Yocan Evolve Donut Coil is a replacement ceramic disk coil designed for the Yocan Evolve concentrate vape. If your device is starting to feel tired, a fresh coil is one of the most practical parts to swap in.
It's built from ceramic and metal, and the donut shape gives it its name. The page uses the plural, so these are listed as coils rather than a single piece, but it doesn't state an exact quantity. If the count matters to you, take a look at the photos before ordering.
Because it's made specifically for the Evolve concentrate vape, it's a good match for owners of that model. Check that your device is the one the page names, since Yocan offers several Evolve variants and coils aren't always interchangeable.
Coils wear out with regular use, so a spare on hand means you won't have to pause when one gives out.
