I saw these at my Drs office and had to shop for them elsewhere. I shoot a lot of Black Powder guns and they really get filthy after only several rounds. These applicators work very well, for cleaning every part of the guns after shooting. They are quite strong and the tips can be adjusted to fit various bore sizes by simply removing some of the material on the tip as needed. They are also handy taking them to the range for cleaning chores during matches and between shots as required. I am glad to have found them at Cascade Health Care Solutions. They have exellint customer service.
