I am in the UK. Which envelopes in your post get your attention
best:

Thin manilla or thick manilla?
Window or no window?
DL(=wide) or C5(=half A4)?
Gummed or self-seal?

I knmow it sounds odd so I explain my thinking in more detail below.

Thanks for any feedback!

White DL window self-seal, judging by the number of boxes of the dammed
things I used to have to shift, I doubt things have changed that much since.

Buy from a reputable source as self seal 'gum' can go off in time, you then
either have to scrap them or use sticky tape to seal them !
