Swiss Gold Gold Filter KF.4 This is a coffee filter made in Switzerland. It seems that this is no longer available for purchase in Japan. I received it but am selling it because I don't use it. There are small dents, overall dullness, and signs of wear such as scratches, but I think they are not very noticeable. The gold part is engraved with "2 4 8 12", and the edge is engraved with "313E". GOLD FILTER #coffeefilter #goldfilter #SWISSGOLD #SWISS #GOLD #coffee #SwissGold #Swiss #Gold #gold
