I used this on a baby bed for about six months. I don't see any noticeable stains or dirt. It has shrunk due to washing, and is now about 72 cm wide and 115 cm long. Pilling will occur due to the nature of the material. I will remove as much as possible before shipping, but please understand. It feels very soft on the skin, and I found it very useful and was able to use it with peace of mind for my first newborn. I am also selling a quilt blanket. Bulk purchases are also welcome. Below is the official product description: Size: 80cm x 120cm [Features] Additive-free: No finishing agents are used, so it is safe for those with sensitive skin. Clean: The processing method is the same as that of sanitary materials, so it is clean. High absorbency: Natural cotton is sufficiently refined, so it has high absorbency. Feel: It has the gentle feel unique to gauze. It becomes more familiar to the skin the more you wash it. Washing: The quilting is durable, so it can be washed. We recommend washing once a week. Quick-drying: It dries surprisingly quickly after washing. Heat retention: Sufficient heat retention as bedding. Defatted cotton has higher heat retention than cotton wadding. Good sleep: It has moisture absorption, breathability, and moisture release, which helps you fall asleep easier and reduces waking up in the middle of the night.
