The colors were great and the size was just what I needed (there were VERY few choices in the size I needed). Unfortunately they are a little too flimsy to really do my job right. I really needed these to bee a little stiffer. They were also a bit irregular in the cutting and the glue was not even or consistent. They would probably work well if I was using them for greeting cards or mailing notes but I needed them to sort and hold small sheet material. The lower back panel is not consistently cut or attached leaving corners that catch and come undone.
I like to make my own little books of poetry. These brightly colored envelopes are the perfect size for a folded 8-1/2"x11" sheet -- and the envelope will accommodate a booklet of more than a few pages which is great because I like the 28 pound paper. I also like the colors because they really stand out; the colors are very clean and strong and there's no bleeding when I use markers to write the address.
