I have purchased them at several places, when I catch them on sale.
The Pulse bottles need to have a narrow top cap to fit, and the Vandy Vape
bottles run about $10/ea +/-.
I think I bought some at Kidney Puncher for $0.50/ea that fit well. I don’t have
my receipts handy atm to check where I bought what and where, but I will look soon.
The Pulse Mech will take a larger top as seen on far left [the dirty pic is just that…
I just got in from mowing a couple acres, lots of dust, eh?]
Center is the Vandy Vape bottle, far right is a 50center ($0.50).
P.S. The Pulse Mech also takes a shorter bottle [total height],
and may take an authentic Wotofo Reserve bottle.
These are the ones I bought from Kidney Puncher [in Pulse BF80W pic on right above].
They are soft and seem very well made, but I wouldn’t have a clue how long they would
last if taken apart daily [or any silicone squonk bottle] because I fill them through the 510.
I have about 30 or 40 bottles because of sales like this, surely many more than I will ever
use, as I have never replaced the first one yet…other than to use a different flavor quickly.
