Two baby sleep sacks from Coperta, different sizes. Purchased new on Rakuten in July 2025. Bought for about 2000 yen each. This is a set of two. Selling because my child has outgrown them. Storage bags are also included. - Condition: Some yellowing is visible, mainly around the collar. 〈Design: Stars, Moon, and Hot Air Balloons〉 Size: S (Approximate for 0-3 months) 〈Design: Lemon Pattern〉 Size: M (Approximate for 3-6 months) My baby slept for long periods when wearing these, providing a sense of security, and they were very useful. Why not give them a try?
