A Beautiful Veneered Pyrex Tank by Mist in the Woods! Wood on the outside, Pyrex on the inside. These tanks are both beautiful and functional. Each Phiniac Phineer is a one of kind work of art! They are handcrafted from start to finish. As is the case with EVERY Phiniac tank, the glass on the inside of each is annealed to further strengthen it and make it more rugged. Phiniac Phineers will provide a worry free vaping experience that gives confidence to the user when using the more "demanding" flavors... Includes caps as well as an extra set of o-rings.
