The Yocan Evolve D Plus Coils – 5 Pack is one of our most rudimentary atomizer packs that feature a dual coil in 12 loops to heat up your select dry herb strains. The coils warm up quickly but do not burn your material. The Yocan Evolve D Plus Coils – 5 Pack also features 510 threaded design which allows it to be easily connected and removed while ensuring a tough and durable hold on the atomizer and on the battery.
