(2-Pack, Medium 8in x 12in) Organic Cotton Cold Brew Coffee Bag - Designed in California - Reusable Coffee Filter with EasyOpen Drawstring Cold Brew Maker for Pitchers, Mason Jars, Toddy Systems

Very easy to use. I didn't submerge the bag into my 2L Mason jar, I kept the mouth of the bag open and around the opening of the jar and screwed the lid over the whole thing. And my cold brew tastes great! Highly recommend this product!

Seems good, comes with brief instructions.

It's super simple, easy to clean and reuse, and makes a nice, crisp, clean cold brew. Definitely prefer it over other methods I've tried. My only thing is the medium size is huge! I make a 2 gallon jug of cold brew at a time using a 1:5 ratio and there was still so much empty pouch leftover that I had to pour 2 or so cups of water out so it would fit. Definitely would recommend a smaller size for anyone making batches for personal consumption.

it works

I love using these bags to make my own cold brew at home. They hold the coffee grounds easily without any escaping and it's very easy to rinse off after. The coffee obviously stains the bags darker but instructions say you can use a little soap if needed for a deep clean. These have become part of my weekly routine of making cold brew and dry quickly once washed. They are definitely worth it for what they cost.
