Is it possible to ship a package by USPS with a letter label?

[b!z]

I'm buying a package from a seller in the US, and he's shipping it with as an "International Letter" with USPS. The thing is, there's no way the item will fit in an small envelope (I'm assuming that's what "letter" means). It definitely would need a larger envelope or small box.

He assured me that the package can still be shipped with the letter label; anybody have experience with this? Am I just confused, or am I being rused?

Depend what they class as a letter. in the uk Royal Mail have some funny ideas of letters and so do alot of mail services. and again depending which company take charge of the letter on your side depends what happens for example of its from the US to the UK and theres not enough postage then either royal mail. or parcel force will accept it and just send you what needs to be made up on the postage. they wont do it if youve never received a letter in that name to that address before.
