Thank you for viewing! This is an adjustable "Velcro" chest belt. Chest belt → This is a belt that fastens in front of the chest to prevent the shoulder straps of a backpack from slipping. It is made for young children who cannot yet use buckles. With Velcro, it's safe! And they can take it on and off themselves with a "peel-off" sound ♡ Recently, I've heard that some kindergartens are specifying Velcro-type chest belts. My child went to daycare, so when we went on field trips, they specified "backpacks with chest belts." The commercially available ones are buckle-type, even for baby backpacks, right?? I was worried about pinching fingers, so I used this Velcro type until my child was about 4 years old. Thanks to that, many children are using it. You can adjust the size to fit the belt width of your backpack. The recommended age is up to 4 or 5 years old, when you might be concerned about using buckles(^^♪ I also make buckle-type ones once children are able to use them.
