These are great bags! My wife uses them for her coffee because the beans she buys don't come in resealable bags. But these bags stand on their own and are very sturdy. The seal works very well too. And the clear side is cool. These bags look very nice next to her coffee grinder.I use them for my... flowers. Some flowers are more fragrant than others and these bags neutralize that worry. I'm sure my dog can smell the flowers in these bags but a human won't be able to. You can also use a sharpie to write on the clear side. And again, it's cool to be able to see into the baggies to see quantity, color, size of the flowers.As for volume, it takes 2 of these bags to hold 1 pound of coffee beans. As for flowers, I can store no more than 2 ounces in each bag.One last note, I have XL hands and the opening is big enough for me to reach in with 4 fingers to snag the gummies inside. My wife can reach her entire hand into the bag.If you're in the market for baggies for your coffee, gummies or flowers, I'm confident you will like these bags.
