Perfect Cold Brew Maker – Durable and Easy to Use
Size: 64 Ounces, Color: Gray
This jar is exactly what I was looking for. The 64oz size is great for making multiple servings and the wide mouth makes it easy to fill and clean. The glass feels sturdy, the lid is truly leakproof, and it’s perfect for cold brew. Simple, reliable, and well-made. Highly recommend!

Simple & effective- Cold brew right at home!
Size: 64 Ounces, Color: Gray
This glass cold brew jar is exactly what I was looking for. It works really well, and I love that I can make cold brew at home instead of stopping out or buying expensive premade coffee from the store — it definitely saves money. I also love that it comes with an oversized pipe cleaner to ensure you get all of this grounds out of the screen when you’re washing it. The only small improvement is the filter screen. It works well overall, but a few minimal grounds do get through. Overall, simple, effective, and a great way to make cold brew at home.

Size: 64 Ounces, Color: Gray
Absolutely love it. The handle and weight makes it easy to hold at 72 years old. The glass container gives my green ice tea a perfectly cold delicious fresh pure taste. It is nice and cold because it's glass not plastic. The pitcher fits my 12 inch high refrigerator door shelf easily. The top is secure doesn't leak .

Perfect Kit For Cold Brew Coffee or Teas
Size: 32 Ounces, Color: Gray
I make coffee many different ways and have been doing cold brew in a regular mason jar without a filter. I just got this set up and am very pleased. The kit comes with a thick glass mason jar of good quality, a filter basket and a lid that fits on top of a wide mouth mason jar. The lid has a sturdy handle attached to it and a secure pour spout with its own snap tight cover. This is a perfect set up for cold brewing coffee. I filled the jar with water and secured the lid. I shook it up and turned it upside down and there were no leaks so it will be safe from accidental tip overs. If you are looking for an easy way to make cold brew coffee then I strongly recommend this simple set up. It is shaped just like a regular Mason jar with a pour spout lid so it can fit almost anywhere a Mason jar will fit. This also looks to be good for making small batches of sun tea with loose leaf tea. Enjoy!
