These nursing pads are made with 4 layers of protection including flannel, cotton terry cloth and anti-pill fleece. The fleece goes against your clothes to create a barrier between the absorbent cotton and your clothes. These pads are very absorbent without creating excess bulk and naturally form to the shape of your breast after washed and dried. They are 4" in diameter. Absorbency is increased after the first few washes. These nursing pads are the perfect gift for the eco-friendly mama! MY FAVOURITE FEATURES Machine wash with like colours warm and dry in dryer. Edges are surged for durability and to prevent fraying. All nursing pads are made by Marley's mom in Eugene Oregon.
