Our 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. CARE + WASHING: Machine wash with like colors warm and dry in dryer.  Edges are sewn for durability and to prevent fraying. Handmade by Marley's mom in Eugene Oregon.
