Review: No leaking when thawing and easy to pour! - Love these!! Ive tried a few different brands and came across these while trying to find a more square bag. They’re super easy to fill up and pour out and they’re the first bag I haven’t had issues with leaking when thawing. They are perfect for freezing flat. Review: Best one for your buck! - Good thick material, holds 6 oz as said, seems reliable and durable. Easy to open and use just like they should. No leaks so far.

A day I get 12-14 bags all holding 6oz in it needles to say I go through a lot of milk bags and it gets super expensive, these are the cheapest most reliable bags I’ve ever bought.
