The Small Alpha® Swab is an excellent general-purpose swab and the small tip is ideal for cleaning small areas, surfaces and recesses. Its laundered, knitted Alpha® polyester head is extremely clean.

Swab features 100% continuous-filament polyester substrate that is heat-molded (thermally-bonded) onto the handle, sealing exposed edges for reduced fiber release and eliminating the need for adhesives. Mini tip with a rigid paddle.
