13, while the diameter measured across the bottom is approx. Condition: Both shades are in very good condition - there are no rips, holes, tears, repairs, etc. All of the lacing on both shades appears to be intact and taut. The applied design on the shade appears to be painted onto the fiberglass.There are some small areas where it looks like there was mild color rubbing (see photos). It doesn't particularly detract, but we wanted to show and mention it for accuracy. Also, there appears to be a few small spots where there is a very faint pinkish color on the fiberglass. All of this can probably clean up quite readily - we choose to leave them alone as it didn't particularly bother us, and is pretty much only seen if you are looking for it. Please ask them and we will respond back to you in a timely manner.
