I used a smaller one for the IRR centers and it has a 4 lb. limit for international. The best source for information on this is the USPS web site. You can really figure out what is the best for your particular situation. I finally learned to google VAT and UK (since that is where my shipments were going) and learned the limits for the customs forms. I would suggest that you do a little research on that aspect prior to sending your package out.
