Was unsure when I ordered these as I usually buy ones that have card back and front. I have posted these several times now and they are strong and good quality AND lighter in weight so cheaper for postage. I have now bought more - this time larger ones and would highly recommend seller and envelopes!!
This is a bargain item which was sent quickly. I bought a size too big incase (like another brand I had) it shrunk in the wash. It didn't , so I highly recommend it - just buy the size which will fit as it doesn't seem to shrink!!
