[Dx-qsl] Self-adhesive air mail envelopes

[Charles Bibb]

Hi, All

I received my 5A7A cards today, with a sticker on the back of the return 
envelope, admonishing me to "help QSL managers to economize time" by using 
a self-adhesive return envelope.

Now, I DO use self-adhesive plain white return envelopes when I send an 
SASE to a US manager.  And, I sometimes use the smaller,
US-standard (3 5/8" x 6 1/2") air mail envelopes with self-adhesive seals 
for foreign managers when I know the card being mailed back is
the small (standard) size.

However, I have never seen a self-adhesive "European-" or "Metric-" sized 
air mail envelope, either 4 3/4" x 6 1/2" or 4 1/2" x 6 1/4".

Anyone know where these can be obtained within the US?

Thanks,
