Crushed Opal FLAKE™ Series COLLAB!

The Cropal series starts with two core designs: OG and ES.

OG is the original flat-base model. It gives more flat-surface contact with the hot floor, which supports strong heat transfer and vapor production. The tradeoff is friction: more flat contact usually means less spin.

ES stands for Extra Spin. It adds a center pivot point, reducing friction so the insert spins more freely. The tradeoff is slightly less flat-surface contact with the hot floor.

So the lineup breaks down like this:

OG = flat base / strong vapor / low spin
ES = pivot point / more spin / slightly less floor contact
At the end of the day, it comes down to what the user values more: maximum flat-contact vapor production, increased spin, or a balance of both.
