This is a baby抱っこ布団 (baby lounger/nest) from Keratta. This is for the filling only. The cover is not included. It was used for about one month during the newborn period. There are no noticeable stains, and it is in clean condition. It is very convenient as it can be washed in a net. When placing the baby on the bed while still in the 抱っこ布団, the "back switch" (the reflex that wakes a baby when laid down) was less likely to activate, and the baby slept well.
