Let me start by saying these Golden State Art clear bags are a game-changer for anyone looking to protect their artwork, photos, or important documents. I've been using them for my 12x16 matted prints, and they've exceeded my expectations in several ways.

The clarity is impressive - it's like there's nothing between your art and the viewer. I love how professional my prints look when displayed in these sleeves. They make my work look gallery-ready without any distracting reflections or distortions.

Durability is another strong point. While they're not meant for sharp objects (as clearly stated), they've held up perfectly for my framed photos and matted artwork. The 1.57 mil thickness feels just right - sturdy enough to protect but not so thick that it becomes bulky.

The resealable adhesive strip works like a charm. I've opened and closed these bags multiple times during art shows, and the seal holds strong every time. Though I did notice you need to press firmly when sealing - one of mine didn't stick perfectly on the first try until I applied more pressure.

They're incredibly versatile too! I've used them for:
- Protecting framed pieces at craft shows
- Storing matted photographs
- Organizing greeting cards
- Preserving important documents

The size is accurate (12 2/5" x 16 1/2") and fits standard mats perfectly. You can even fit multiple backing boards if needed. At this price point, the value is excellent - much cheaper than specialty framing supplies but with similar protective qualities.

A couple minor drawbacks:
- The plastic can develop slight creases if stored improperly
- Some bags have punched holes that occasionally appear on the front side
- They're not suitable for sharp-edged items

Overall, these clear bags have become an essential part of my art business toolkit. They keep my work pristine during transport and storage while maintaining a clean, professional presentation. For anyone selling or displaying artwork, these are absolutely worth trying!
