This was a large map, but not too large as I wanted to be able to read the cities and larger roads. I wrote on mine with a CD marker which worked well (regular markers were able to smear and wipe off if rubbed gently with a kleenix (or a shirt)). Excellant quality and thickness of lamination, and it came rolled up in a tube (so it had no damage to me in shipment) and when reverse rolled for a day or so it straightened out pretty well so I could work on it.
