Our cotton swabs are made with long cotton fibers and a simple methyl-cellulose binder. They provide extremely low levels of extractable residue, particles, or fibers, and the heads are far more tightly wrapped than those of traditional cotton swabs, making them ideal for critical applications and fine detail work. These are especially small, perfect for very small areas. The double-ended swab features 2 round cotton heads 0.1″ diameter x 0.05â€ long heads on a 3 inch long paper shaft. 25 per package.
