We have spent several hours looking for a supplier for the products/ brand names you are interested in, but unfortunately we are only able to locate a supplier for Paul Frank products, please visit this link: Link hidden: Login to view
For both LeSportsac and Kipling we were unable to locate any suitable suppliers. It could be that these product brand names are sold through authorized distributors only. We suggest that you contact the manufacturer directly and ask for their authorized distributors or inquire how you could become an authorized distributor yourself.
Here's the link for wholesale/distributor application for LeSportsac:
