Since baseball cards aren't very big, you won't need a large envelope.

I would suggest putting your request in a standard-sized envelope, and then send a SASE big enough to fit the cards in (up to the standard-sized envelope.)

They probably won't get bent, because you'll be using a standard envelope size, so you probably won't need to add cardboard. I have no problems to date with my small 6x4 photos being sent to and from the celebrity. None of the photos I have received back have been bent (with no cardboard in the envelope.) You may want to write "Do Not Bend" on the envelope just to make sure though.

I would send a greeting card envelope. If possible don't forget to put in a piece of cardboard, so that the card doesn't get bent.

hey,

my brother is a HUGE fan of sports and i usually have him send his in a medium sized envelope. not too small incase they send something back, and not too big, so you don't have to pay that much for postage.

*sorry i don't know the measurments*

I personally use the 10.4 cm by 24.1 cm. regular business envelopes. For the SASE I use 9.2 cm by 16.5 cm standard envelopes. But as RentRocks said any envelopes that the card will fit in should work fine!

Hi bizarregoldenone,

If you want to send baseball cards, then you don't need a 9x12 or 8x10 envelope for either the envelope you send your stuff in or the SASE. Any size envelope that can fit the cards should be fine.

If I want to send baseball cards to players, what size envelopes should I use for the sending envelope and for the SASE? Thank you.
