Do you know what MANILA stands for? Multipurpose Addressed Non-adhesive Inexpensive Lendable Applicator. They changed it to manila when they (whoever "they" are, you know people who make words and stuff) realized that the whole phrase wasn't necessarily easy to say.
Our manila envelope or (the multipurpose addressed non-adhesive inexpensive lendable applicator), whatever you chose to say, doesn't have to be explained really (but we will anyway). You can use it for many different purposes, it can (and should) be addressed (with the correct amount of stamps), it has either a clasp or no clasp but definitely no adhesive, not that expensive, you can lend it to anyone you want AND it is applicable to anything really. Use it for any of those adjectives that JAM totally didn't make up. Manila is seriously an acronym! It is, really!
