If you choose the framed option it will be sent in a front opening A3 aluminium snap frame with mitred corners.
Please note if you select the sent folded option it will be sent folded so there will be a crease in the middle, this is to keep postage to a minimum. If you want it to be sent flat then please select the sent flat option. This is more expensive to post as it will be classed as a parcel and not a large letter so please ensure you select this option if you don't want it folded.
