BabyBjorn Baby Carrier HARMONY in Anthracite. Retail price: 34,100 yen (tax included). A popular model that can be used from newborns to around 3 years old. 【Usage Status】 ・Usage period: Approximately 8 months ・Frequency of use: About once a week ・Used less frequently as other baby carriers were also used. ・There is one loose thread. There is some fuzzing characteristic of the fabric, but it is generally clean (please check the photos). 【Personal Impression】 I have used other baby carriers, but this HARMONY was the most comfortable for my shoulders and back, and I could use it for long periods of time without any problems!
