Can I have bleed on these Envelopes?

Yes, this is the only Envelope product that allows for artwork with bleed. With the other two printing methods, the envelopes arrive already cut and glued into envelope shapes, whereas with the Full-Colour envelopes, they are printed on a flat sheet, then "converted" into envelopes. During this process, they are die-cut, so as long as the proper amount of bleed is given in the artwork, the final envelope will have printing right to the edge.
