The price, 20 bucks and it came with two 100 round tubes.
The little pouch is handy for tools.
I thought I got a killer deal but when I put my tank in the tank holder, it ripped right threw! My mom sewed it and I just thought, It'll never happen again but next time I played it ripped in a different place.
Very cheap seams or thread.
If you get it, double sew the seams before you put a bottle in it.
However, I do not recommend it.
