PICO ange] [Recommended by the dermatologist clinic director] 100% natural cotton Angel Swaddle Comfortable Swaddle [Double zipper for easy diaper changes] All-season, L size (6-8.5kg) [Double zipper] The double zipper opens from top to bottom, allowing you to change diapers while the baby is still in the swaddle by opening the bottom zipper. Also, a zipper cover is used at the neck to prevent the zipper from hurting the baby. * [Hands out. Can be fastened with buttons] 2-way specification that allows you to put your hands out or close them. Fastening the snap buttons prevents the baby from scratching their face. You can take your hands out by opening the buttons, so you can also trim the baby's nails while they are sleeping. It is recommended to open the buttons after the baby learns to roll over. By putting your hands out, the baby can roll over with peace of mind. I think I used it for a total of 10 days, using it on and off. There are no noticeable stains, but There is some fluffing due to several washes. Thank you for your understanding!
