This is a fluffy blanket made of 100% cotton. It's about 3-4 millimeters thick, but please consider this an approximate measurement taken with a ruler. I used it to lay down for taking care of a baby, or to cover them during naptime. I had several blankets that I rotated through, so it's not very worn. It was washed with unscented detergent. No pets, no smokers. 65 x 53 centimeters My child has grown up and I no longer have a use for it, so I would be happy if someone could use it. It has embroidery from the maternity hospital.
