The 'Deposit Kit' contains a plastic shipper for protecting your test tubes, a pre-paid UPS waybill, plasmid forms (if you did not enter your cloning data online), and a pouch along with shipping instructions for mailing the plasmids to Addgene. International depositors will also receive a deposit kit by way of UPS, but the pre-paid return shipping material will be through FedEx and additional customs forms will be included.
