Let me start by saying these storage bags are a lifesaver for organizing my art supplies. The variety of sizes (A3, A5, and 19x25 inches) means I can store everything from large posters to small brushes without any hassle.

The transparent PVC material is a game-changer - I can instantly see what's inside each bag without having to open them. The waterproof feature gives me peace of mind when carrying my precious artwork in rainy weather.

However, I did experience the zipper issue mentioned in other reviews. One of my A3 bags had a stubborn zipper that kept getting stuck. While the seller was quick to resolve the issue with a refund, it's something to be aware of if you need reliable zippers.

The handles are surprisingly sturdy for nylon straps. I've carried heavy art projects in the largest bags without any tearing or discomfort. The 9.5-inch handles make them comfortable to carry over the shoulder.

For diamond painting enthusiasts like myself, these are perfect for keeping all those tiny drills organized. The medium transparency is ideal - it shows enough content while still maintaining some privacy for valuable items.

My only other complaint would be that the largest size (19x25 inches) tends to flop open when not completely full. Some internal structure or stiffer material would help maintain shape better.

Overall, despite minor flaws, this set offers great value for artists and organizers who need versatile storage solutions across different sizes.
