This is a Konny Swaddle! I tried it on my newborn once, but it was too big. When I tried it again when my baby was 4 months old, it was too small (T ^ T), so I'm selling it. The size is listed as 3M by the manufacturer, but it's tight on my 70cm baby, so I've listed it as 60cm. It's only been tried on twice, so there's no sign of use, but please forgive any oversights as it has been stored at home. I would appreciate it if you could consider this item understanding that it is a used item. ^_^
