What is a letter size manila envelope?

A letter size manila envelope is a type of envelope that is designed to hold and protect standard letter-sized documents (8.5 x 11 inches).

These envelopes usually have a gummed flap closure that can be moistened and sealed by pressure.

Things to consider before buying

Before purchasing a letter size manila envelope, here are some important factors that you should consider:

4. Quantity

Consider how many envelopes you need before making a purchase. Buying in bulk can save you money in the long run if you frequently use these envelopes.
