12/pk Yellow Microfiber (245 GSM) 16" x 16" towel (sold at $1.66 ea in case quantity of 12) - A perfect towel for just about everything. We like keeping two colors. One for use in contact with silicone dressings and another strictly for windows. Not all microfiber is the same. Smears and streaks are often not the product problems but a poorly constructed towel. Even though these towels are light at 245 GSM they are crazy absorbent and perform better than towels tested at twice the weight.
