Mughart Swaddle Mesh - Design: Star pattern, Penguin pattern - Material: 100% Cotton - Size: M size (Weight: 6-8.5kg) Thank you for viewing. This is a set of two M size swaddles for summer. I am selling these because my baby has outgrown swaddling. I switched to M size and my baby quickly outgrew them, so each was only worn about 3 times. There are no stains or fraying, but please understand that this is a personal inspection. These swaddles were a great help during the period when my baby's sleep was unstable. I hope the next baby who uses them will sleep soundly!! If you want to buy them separately, I can't sell them for exactly half price, but I will consider it, so please feel free to ask.
