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. This single round cotton head measures 0.2â€ diameter x 0.6â€ long (0.5 x 1.5 cm); the wooden handle is 6â€ long. The combination of a small head on a longer shaft will allow access to more deeply recessed areas than our traditional cotton shaft, double-head swabs are able to permit. 100 per package.
