eBay

I'm looking to get some Dymo 99019 shipping labels for my Ebay packages. I've seen many people saying to make sure to get American ones, not Chinese,as Chinese can wear out the print heads prematurely. Where can I find 99019 labels that are compliant...

I have a Dymo LabelWriter Wireless printer and 2-5/16" x 4 (30256) shipping labels. Can I use them to print labels for my Ebay packages? If not, what size can I use that's compatible with the printer I have?
