I purchased a lot of these filters on a website to use with my water absorber, but the water absorber broke. Since the same water absorber is no longer sold, I have 14 unused filters. I only have 14, so I can't sell them in sets of two 6-packs (＞人＜;) Before purchasing, please comment if you'd like to buy more than 2. ^_^ 2 filters for 300 yen 6 filters for 800 yen 8 filters for 1300 yen All 14 filters for 1800 yen (shipping will cost over 750 yen) I will respond to your comments. I am also selling these on other sites, thank you for your interest m(_ _)m
