The material will have a certain degree of flex depending on the sheet size. We would recommend ordering a small sample first for you to check if this would be suitable for your requirements. Alternatively, we do supply 1.5mm opal material which will give you a greater “flex” to it then our 3mm acrylic. For any further assistance, please do not hesitate in contacting us. Kind regards Sign Materials Direct info@crestarltd.com 0203 667 7067 **Q: Does opal mean translucent?** A: Translucent would be a better description of this product, it is white in appearance allows light to pass through but cannot be seen through. I have used it to diffuse a light source and for this purpose it works well. **Q: how to glue it on the wood frame?** A: I drilled mine and used pop rivets to attach it to some aluminium ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by S***N on 28 March 2026* Used as a diffuser in a floor lamp, great quality, well protected when it arrived, and not to bad to cut, I needed to cut a circle and just used a multitool. ### ⭐⭐⭐⭐⭐ Good quality *by C***O on 1 April 2024* Perfect for my commercial photography project. I used it with different products and the results are good. Good quality, perfect thickness, easy to clean. ### ⭐⭐⭐⭐⭐ Value for money *by M***X on 16 August 2024* I wanted more cutting 'plates' for my old die-cutting machine and as I've got a mixture of dies of various types and makes I more often than not need to use shims, so these 3 mm acrylic sheets fitted the bill perfectly as they're so versatile. I can easily use them stacked together, but having two thinner sheets means you've actually got 4 cutting surfaces. Excellent service, a range of sizes and such good value in comparison to branded versions. ## Frequently Bought Together - 3mm Perspex Opal Gloss Acrylic Plastic Sheet 16 Sizes to Choose (297mm x 210mm / A4) - 3mm White Gloss Acrylic Sheet 16 Sizes to Choose (297mm x 210mm / A4) - 3mm CrestGlass Black Gloss Acrylic Plastic Sheet 16 Sizes to Choose (297mm x 210mm / A4) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/52658291-3mm-perspex-opal-gloss-acrylic-plastic-sheet-16-sizes-to](https://www.desertcart.co.uk/products/52658291-3mm-perspex-opal-gloss-acrylic-plastic-sheet-16-sizes-to) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
