Does the white envelope fit inside the brown envelope? i want to use that as sae to send to people to get things signed.

I have no idea, however, the white envelope could be folded in half, and would then fit comfortably in the hard back one. This is a common pratice, as no harm is done to the white envelope simply by being folded in half., it is still perfectly serviceable. Bob

Would these suit sending printed wall art? One page wall art with one sheet backing board, inside cellophane then inside one of these.

I use these for just that purpose, however I also include another sheet of thin A4 card, just for extra safety. So, the picture is first wrapped in a folded A3 sheet of acid free tracing paper, then I insert that into the envelope and add the additional card on the other side of the picture to the hard backing on the envelope (I'm sure you guessed that!). Also, for added safety, I tape the envelope flap down with sellotape. I think the existing sticky strip is probably sufficient, but it's rather narrow and I don't like to take chances. It's still light enough for large letter rates and I haven't had any pictures returned damaged.

How much do they weigh each?

The one I just received is 50g. The previous batch that ordered was 54g
