This document is about buying Yokohama balloons from Japan.

They have a great track record, at a cost.
Other alternatives exist, but this document is only about Yokohama.
            

You have two options, and they both get you 10 balloons (minimum order quantity):
1. Medium-fast and most expensive (4 days, $250)
2. Medium-slow and less expensive (18 days, $209)

Medium-fast and expensive - buy direct from Yokohama.
Medium-slow and less expensive - use a forwarding service who can save you money on shipping.

If you want the forwarding service, see below.
            

Tenso is a forwarding service.
