These 155 wave-style filters are fully compatible with the Etkin 2-cup Coffee Dripper.
Made in Japan.
I ordered filters through Kickstarter for the Etkin dripper not knowing what brand they were, and they turned out to be the Kalita 155 size filters when delivered. I have no problem with using Kalita filters but I have a whole lot of them already and would not have ordered more if I knew this brand being offered and sold - hence the 4 stars. Maybe mention that on the site in case people have that brand.
