Isn't this a nifty invention? Instead of investing in new gear for pour-over coffee at home, one can just grab a disposable coffee dripper. It'd be great for travel too. For some reason I haven't seen this sold in the US but when I was in Korea, it was everywhere! I'd never seen such a product before so I brought back a box to enjoy at home. So cool, convenient, and best of all: no coffee grounds to clean up.
