I Can Never Finish a Carton of Milk—This $13 Tool Keeps Dairy Fresh for ‘Double as Long’

I’m not a big cereal eater, and I haven’t had a glass of milk since childhood. Still, I always like to have a carton of some kind in my fridge. I’ll add a drop of oat milk to my morning coffee and like having the option to bake at a moment’s notice. The only problem is that since I live alone, I can never finish a carton before it starts to spoil.

Tired of pouring money down the drain each month, I scoured Amazon for a solution. According to Amazon shoppers, this airtight glass jar keeps milk, cream, and non-dairy alternatives fresh for “double as long” as standard cardboard cartons. I’m snagging this simple solution for just $13.

Syntic Square Airtight Glass Milk Bottle

The Syntic milk jar has a 32-ounce capacity and is embossed with measurement markers in fluid ounces and milliliters. At 9 by 3 by 3 inches in size, shoppers say it can easily fit into the fridge door shelf. The bottle comes with two stickers and a dry erase marker, which you can use as reusable labels to help you keep track of what type of milk you’re storing and when you bought it.

The bottle comes with two lid options: an airtight screw-on top and a pouring spout. The spout makes it almost impossible to spill or make a mess when pouring. One shopper said even a toddler could use the flexible yet precise nozzle. Since it has vents at the top, it’s not ideal for long-term dairy storage but it’s perfect for beverages you plan to consume right away. For milk and cream, use the screw-on, airtight cover to lock in freshness and avoid leakage.

You can use this versatile jar for homemade nut milk, fresh juice, iced tea, cold brew, and so much more. It would also double as a great carafe for your bedside table. Some shoppers even store grains, beans, and other dry goods in theirs. It’s easy to wash it between uses. The jar features a 1.4-inch opening, wide enough that you can reach in with a cleaning brush, according to the brand, and it’s also dishwasher-safe. 

Whether you’re hoping to extend the lifetime of your store-bought milk or want to bottle your homemade creations, this is the perfect solution. A silicone seal keeps freshness in and oxygen out, so your favorite sips will taste great for days. In fact, one happy shopper said their homemade almond milk “lasted more than a week,” thanks to the bottle’s tight-fitting lid. 

I can’t think of a reason not to buy this do-it-all jar. Snag yours now for $13, or grab a four-pack for just $23.
