Gusumin Swaddle to Prevent Rolling Over I tried this a few times during the early rolling-over phase, and there is some pilling and a used feel. I think it's fine for normal use ^ ^ I have washed it several times. This is a used item, so please only purchase if you don't mind. I will send it in simple packaging. - Brand: GUSUMIN - Target age: Newborn to 9 months - Material: Polyester
