This is a CALIN mother's bag. It's the older model with Velcro closures. It has been used, so there is some staining and signs of wear. Please understand that this is a used item before purchasing. The strap has buttons that can be detached, but the buttons tend to come undone when the bag is heavy, so I have sewn them in place to prevent them from detaching. Therefore, the strap cannot be removed, so please be aware of this before purchasing. It will be shipped compressed, so please understand.
