White Collar Grime (ORIGINAL) as a shirt collar protector or collar protector prevents ring around the collar stains, tames tags, and covers up itchy embroidery, making shirts so much more comfortable to wear. To prevent issues with neck sweat, simply cut off the desired length of 100% super-soft cotton, stick it to the inside of your collar, and go about your dirty work. Peel off and dispose before putting your shirt in the laundry. Voila! No ring around the collar stain, no hat sweat stains, no nonsense. <br><br>Hat sweat stains are never cool and always gross, but if you throw your cap in the wash, you're risking permanent damage from colors fading, shrinkage, or worse. Protect it with White Collar Grime (ORIGINAL) or, even better for hats, new White Collar Grime (THIN), which is thinner and stickier. Contains: 1 roll / 10 ft x 1.25 inches
