Ash Billiard Sunset e-pipe is handmade in small batches, typically ranging from 3 to 6 pieces. The bowl is hand-carved out of ash wood, and the shank can accommodate atomizers up to 24mm thick. The acrylic mouthpiece (drip tip) can be attached to any flat top tank. Atomizer is not included, but the Berserker V3 MTL or KHW Mods Dvarw MTL 24 FL would be ideal. If you prefer tanks with factory-built coils, then the Innokin Zlide 24mm is the right choice. The e-pipe is powered by one 18350 Li-ion cell (not included). As these are small batch products made by hand from real wood, the pictures may not be identical to each sold e-pipe. However, the differences are minimal, and pipes within a batch are very similar to each other.
