I only dropped 1 star for the thickness discrepancy otherwise would have been 5. ## Frequently Bought Together - Sign Materials Direct 3mm Ruby Red Transparent Gloss Cast 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) - 3mm Cobalt Blue Gloss Cast Acrylic 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.pt/products/54395810-sign-materials-direct-3mm-ruby-red-transparent-gloss-cast-acrylic](https://www.desertcart.pt/products/54395810-sign-materials-direct-3mm-ruby-red-transparent-gloss-cast-acrylic) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-06*
