I'm really pleased to be able to share with you this website where you can order a variety of Hanji papers from Korea and it's all in English !!! The store is based in Daejon, Korea.
HAMINBRIDGE (Thehanji) was established by Moonyang Park in 1983. It's a family owned 2nd generation business and they have a factory in Junju. They also have a factory in China where some of the paper is made. The website is at www.thehanji.com and it provides a selection of specialty Hanji paper (Korean paper) and products.
I ordered some papers from them recently to see what it was like and they were extremely efficient in dealing with the order and it was here in the UAE within 5 days so I was really impressed. The prices were good and they even have some on special, the paper is beautiful and the ease of ordering was amazing.
They do sell rolls of paper, traditional papers and lanterns but overall I did think the range was a bit limited for what I want. I'd love to see some more plain colours, bleaching papers and patterned papers but this is certainly a great start.
