Valley View Vapes - Home of the Triple V Tanks Your Home for Quality Inexpensive Vaping Supplies and Accessories If you haven't seen my website before I encourage you to go check it out. I sell the least expensive Polypropylene and Pyrex Tanks on the internet. If you find a lower price (for the exact same item and quantity) anywhere else, I won't just match it, I'll beat it! Well, it's finally available. This is the tank I set out to design when I first started my business. Introducing the Sidewinder! The very first of it's kind. A Pyrex Tank with a side fill hole. The best of both worlds as far as tank design goes! Tank body is made of heavy duty Pyrex (borosilicate glass), it includes a Genuine Boge 2 or 3 ohm Cartomizer, black Delrin end caps and your choice of Screw and Drip Tip color. It's available in both 4ml and 7ml sizes.
