I ordered a 3ml polypro tank, I should mention this is my first tank. I was worried that it would be too big and bulky but I am happy to say it looks marvelous on my kgo. The thumb screw fill hole is so convenient, the tank wall is thin but remains very sturdy. Comes with a boge carto and a nice looking drip tip for less than 10$ shipped. Also would like to thank Ray for the handwritten thank you with on the shipping slip, a nice touch that lets you know it was packed by a person not a robot. I would rank them 5 stars.
