Set of 12: Each towel is made of a single layer of Organic, Unbleached Cotton Birdseye ‚Äì a strong yet light weight woven fabric that is highly absorbent and mildly exfoliating. The fabric has been carefully cut and serged around the edges to create sets of 12. The fabric is pre-washed, measuring 5" x 8". With repeated laundering, they will shrink a bit and washing without fabric softener will keep them at their maximum absorbency. With each subsequent wash, the fabric will get softer and more absorbent.
