This is a backpack that can be attached to the front of a baby carrier. It was very useful when going out because you can take out your wallet, handkerchief, etc. while carrying your baby. Please understand that this is a used item. You can't quickly take out your luggage from a shoulder bag... When your luggage increases, both hands are occupied and inconvenient... The pomochi backpack, conceived by a current mother, with the concept of "going out with your baby hands-free." It's a new style of mother's bag that turns your usual baby carrier into a + mother's bag. In principle, it can be used with all types of baby carriers that have shoulder straps and a waist belt.
