Let me start by saying these bags are a game-changer for storing artwork! The 2 mil polypropylene material feels sturdy yet lightweight, and the clarity is impressive—no foggy plastic here. I’ve used them for matted watercolors, and the 22x30" size fits perfectly with room to spare.

The resealable adhesive strip is *chef’s kiss*—it sticks securely but doesn’t leave residue when reopened. Unlike cheaper sleeves I’ve tried, the flap actually stays closed instead of peeling up over time. Pro tip: Fold the flap outward before sealing to avoid accidental sticking to your art (a minor gripe mentioned in reviews).

Where these really shine? Portability. I hauled 10 protected pieces to a gallery show in a flat file, and zero dust/damage occurred. The bags also stack neatly without slipping—a lifesaver for my chaotic studio shelves.

One quirk: The shipping fold marks worried me initially (as other users noted), but after weighting them under books overnight, the creases vanished. Not ideal for immediate gift presentations though.

Compared to shrink-wrapping, these save SO much time. I recently reused one sleeve five times for jury submissions—the adhesive still works like new. At ~$0.50 per bag (25-pack), they’re pricier than flimsy alternatives but worth every penny for archival protection.

Size limitations exist (I wish they offered 18x24"), but their range covers most standard formats. Pastel artists rejoice—the thick plastic doesn’t dull vibrant pigments as thinner sleeves do.

Verdict: 9/10. Nearly perfect for pros/hobbyists needing durable, reusable protection. Dock one point for shipping folds and limited giant-size options.
