Sorry, Mike. I saw this only now.
Toyo bellows do not have the corner tape installed by the factory. But most Japanese photographers tend to take very good care of their equipment, and tape them as soon as they receive the bellows to avoid problems later. I am constantly surprised at the excellent workmanship of almost every Japanese person. This is not just in specialized tasks, but even in everyday life. I suggest you do not worry about the bellows. You've got a better deal.
