Mesh material swaddle with a dinosaur pattern. It's breathable and very stretchy, and seemed comfortable with a snug fit despite being slim-fitting ^_^ There's a faint stain on the hand area. After giving the baby a laxative called Malt Extract, the baby put their hand in their mouth, and it got stained. I'm offering it at a reduced price for anyone who doesn't mind! 100% cotton Swaddle blanket
