I picked these up, and they work surprisingly well.

$0.10/envelope, and they have zero feathering or anything.

As it so happens, I've recently tested out a few different envelopes. The finest I've run across thus far are these Clairefontaine triomphe small envelopesthat I purchased at Goulet Pens. They are thick, smooth, and lined on the inside with white tissue paper. Not cheap: over $10 tor 25.

A close second, but much more cost effective were these Azaza envelopes on Amazon. No tissue paper lining, but thick, smooth, and for $13/100, a real bargain.

There's part of me that just wants to snap up as many of the Clairefontaine as I can fine but I'll probably stock both and use the Clairefontaine for my most valuable mail. If you're in the US, I'll send you samples of each of you'll message me your address.
