Just to let you know, those carriers are not genuine Hello Kitty products.
All Hello Kitty brand products (in the US), are licensed to Little Lily.

You can also tell that those products are fakes because that particular company used that same fabric pattern to produce a pet bed among other things.
Not sure if you guys care about stuff like this, but thought I would at least inform you.
