Correct. It's tiny and comes in a little watertight cannister. I keep the cannister full of water so it is already wet. Open it up, put it on the vape and after a few draws you can dunk it back in the cannister to re wet it (if on the go) or invert the vape and dip it in a glass of water if at home.
It moisturises via the ceramic inside holding a little water and cools via the water and by virtually doubling the length of the vapour path.
It's also very tough. I have dropped mine numerous times onto tiles, concrete, grass etc no problems.
I'll try to post a photo later ifi have any
Edit- photos.
I really can't recommend these enough. With a bit of mflb silicon i use it with my vapman, vaponic and vapcap, and a bit of fw3 silicon allows it to fit my milaana stem.
I went to go and buy a second one at full price of $30 australian (it is that good for my purposes....), but with this sale i will have a dedicated one for each device. Awesome.
