Ultra-absorbent microfiber cleaning swab.
Works as advertised - durable, easy to clean, folds into nothing in my case.
Even after soaking my slide in warm soapy and using a swab there always seems to be debris in the slide tubes. I got this swab to run through after playing / cleaning. I was impressed by the substantial weight on the end of the cord--it readily falls through the tube without any thought of hanging up. The cord is securely fastened to the swab. After a couple passes through the bore it was spotless! Great thing to have in your case and easy to use.
This swab is helpful for drying out my outer slide. The terrycloth towel sheath doesn't get all the way down into the slide bow. This does. Cannot go through a small bore inner slide.
