Alright crafters and photo enthusiasts, this OLYCRAFT pack of 30 plexiglass sheets is seriously going to become your new best friend for all kinds of projects! Each sheet is 6x4 inches (that's about 150x100mm) with a 0.4mm thickness - which might sound thin, but it's actually more flexible than standard glass while still being impact resistant. This flexibility means it protects your precious photos effectively without being prone to breaking like traditional glass can be. The transparency is excellent - it's as clear as glass, so you can easily see through to your photos or artwork without any distortion. Now, here's something important - each sheet comes with protective films on both sides to prevent scratches and damage during shipping and handling. You'll want to peel these off before using them in your projects (though I'd keep them on until you're ready to use each sheet to avoid accidental scratches). There might be some fingerprints on the surface from production, but don't worry - just give them a quick wipe with a damp cloth and they'll be good to go. The applications for these sheets are practically endless - use them as replacements for broken glass in photo frames, as protectors for artwork, as plastic canvas for various crafts, for laser engraved signage, as tabletop protectors, and so much more. Having 30 sheets in the pack means you've got plenty to work with for multiple projects or to have spares on hand for future needs. They won't yellow or crack over time like some cheaper materials might, and they're significantly lighter than glass, which is great if you're shipping framed items or just want to reduce weight in your displays. Whether you're a professional artist, a hobbyist, or just someone who wants to preserve special photos, these acrylic sheets deliver quality and versatility at a really reasonable price point.
