This is the kaico pasta pan, model k-003, designed by Makoto Koizumi. I purchased it on Rakuten in 2010. It can be used with both gas and IH cooktops. I'm selling it because I haven't been using it much lately. The handle on the stainless steel inner mesh part tends to come off easily, but it can be put back on by widening the handle and re-inserting it. I've been using it for 10 years, so there are many chips and stains on the enamel, but it's still usable. The original box and instruction manual are not included. This might be of interest to collectors of Makoto Koizumi's designs. Thank you. Feel free to ask for a price reduction.
