I purchased 2 of these 3X3 meter curtains when I lived in Udon. I'm back in the Pattaya area and only need one so the other one is for sale. I paid 1,900 each and the reason it was so cheap is because they don't have the cable/string that allows you to roll it up.
You have to roll it up manually and then tie it---no big deal unless you plan on rolling it up and down several times a day.
Good condition and about a year old.
I would consider a trade for an old 15-17 inch original black cast iron skillet.
Cheers....
