Cotton hot air balloon and bear-patterned sleep sacks to support comfortable sleep. - Design: Hot air balloon and bear pattern - Material: Cotton (likely) - Pattern: Bear stripe pattern - Pattern: Hot air balloon design Thank you for viewing. These are size 2-7 years old (45cm x 80cm). I used them for two seasons, but I'm selling them now because I don't use them anymore. I purchased both at 45cm x 80cm, but perhaps due to product differences, the hot air balloon one seems longer and slightly narrower. Retail price: 1750 yen (per piece)
