I love flat mail

Hi, could you specify the size envelope/number of items/weight or amount of stamps?

Yes, is there a minimum weight expectation? Or a range of weight/size of envelope?

roosje- I reviewed the description. It should be a letter sized envelope and the weight could be 30-50 grams. It is a flat mail. The number of stamps depends on each country postage costs. I just know it is an affordable swap. As a flat mail, the envelope does not need to be thick. However, it is up to the sender. Most of items are paper stuffs like postcards, notecards, stickers. So, it is easy to send a great amount because paper items don't weight too much. Senders don't need to purchase anything. They can send the things they already have. I won't give a minimum value because some people like to send extras, some don't. So, it is up to the sender.

Cariboocarol- I didn't want to put a value or price because a flat mail does not need to be a thick envelope. About the size, I put a letter size. But, if the sender wants to send a bigger size. Then, it is up to the sender. About the weight, what do you consider as a flat envelope? What is your local post office's requirement? My post office only accepts paper stuffs until 50 grams as a flat mail. But, if the envelope contains items like keyrings, pens, etc. Then, I don't pay the same price as a flat envelope. So, it depends on the region and what your local post office requires.
