Sleeper Baby Sleeping Bag Rakuten Price: ¥6480 The sleeping bag has a zipper around the perimeter that can be opened. Convenient for changing diapers. There is a small internal belt to secure the baby and prevent them from kicking off the covers. Used only once. From the beginning, the Velcro had weak adhesion, so I re-made it by sewing on buttons. Washed only once after use, and it still feels fluffy. *From the product page* Main Specifications 【Size】: Approximately 88x46cm 【Fabric】: 100% Natural Cotton 【Recommended Age】: 0-3 years old 【Other Uses】: Can be used as a sleeping bag for strollers. 【Safety】: The triangular windproof cap is designed to protect the baby's head. 【Cold Protection】: Shoulder buttons: Prevent wind from entering.
