Hmm, I see your point(s). It might not work very well as it shows.
I do travel some & thought this might be a solution to not carrying a syringe. If it worked, this could also be good for general carrying around
juice---to dripping, topping off carts or filling tanks on the go---or could just be a PIA!
This started with me searching for a way to carry juice for refilling tanks in my ego pcc as the original bottle has a lot to be desired. I do have a small glass vial with tiny glass dropper that works when one is patient---the one above just looked intriguing & could be carried easily in purse/makeup bag kind of thing.
I use the flux type at home some---but syringe is used most as I don't have that all day vape flavor sorted out yet.
Love the steel topped one---I'll keep the reference.
Thanks -- and if anyone else has a source for one with the needle in the bottle, let me know.
