So a friend of mine got a box of Idk what they are, but the local vendor insisted they had never had them when they are the ones that sold her them. They are a little longer than a boge cartos and have two holes at the top once a plug is removed to drip into. When one died she tom it apart it looks like an atty with a very tiny amount of filers that sits just on top of the atty. She uses and eGo as do I so I know they are tresses for them. I have scoured the net looking for anything similar but I am at a loss. she really loved them and would love to find where to get more. She tossed the box because she thought she could get more from fsusa but again they claimed tgey never stocked them when that is where she got them. I would love to help her get her hands on some more if possible. Thanks.
