The COIL V-SEE-THROUGH QUARTZ (4PK) by Lookah is a replacement type V coil designed for use with the Lookah Seahorse vape pen range, including Seahorse, Seahorse Pro, Seahorse Max, Seahorse 2.0, Seahorse Pro Plus, and Seahorse X. Each pack contains four coils for your convenience. These 510 coils feature a porous quartz tip that ensures a pure flavor when dabbing wax and concentrate. To maximize the lifespan of the quartz tip, it is important to fully burn off all the concentrates after each dab. Leaving concentrates on the tip or inside the airways can cause hardening, potentially damaging or wearing out the coil prematurely. Please refrain from cleaning the quartz or ceramic tip with the cleaning brush or any liquids/solvents, as this can harm the tip. Additionally, avoid dipping the coils directly into the concentrate, as it can oversaturate and clog the coils, reducing the vaporization rate. Instead, lightly touch the edge of the tip on the coil to the concentrates. These 510 coils are specifically designed to fit and work with the entire Seahorse vape pen range. They feature a transparent tube that showcases the vapor, while the porous quartz tip vaporizes the wax concentrate when heated. This upgraded coil combines the best aspects of type 1 and type 3 Seahorse coils
