For swabs I have no good answer. One oldschool method was to attach them to a lanyard - and strangle yourself crawling through a bush
You could use one of the spring wound extending ID card/key fobs - but they are also a nuisance when using them to clean a barrel in game.
Someone may sell some, but the general answer is to accept that sometimes you need to keep buying them and also finding them.
At one point in time I knew how many Exalt barrel maids that I had bought. At no point in time would I possess that quantity, sometimes I had a couple more, most of the time I had a couple less. I expect that few of those I own today were bought by me
