Swaddle Up Transition Bag Bamboo Lite Size M (Approximate weight: 6-8.5kg) Stage 2 (Sleeves can be removed) Retail price: 7,400 yen I received this from someone else, but my baby started rolling over before I could use it, so I haven't used it with the sleeves attached. The main body (torso part) was used for about a month. I checked the operation of all zippers before listing. Please refrain from purchasing if you are concerned, as this item has been stored at home. I will ship it via anonymous delivery.
