Comes with a adhesive backing and worked for what i needed ### ⭐⭐⭐⭐⭐ Excellent! *by on Reviewed in the United Kingdom 1 October 2025* Excellent product, did exactly what it said it would, and cheap! ### ⭐⭐⭐⭐⭐ Very convenient and versatile *by on Reviewed in the United Kingdom 18 January 2024* Very versatile and the optical properties absolutely work. However, as it is a polymer film that one applies like a smartphone screen protector, the physical properties are similar too; they're not fully scratch resistant and from other comments I have seen, not heat resistant either. How well it fits to your requirements, depends on one's craft skills.But for general use for when you need a filter as such, I have zero complaints. ## Frequently Bought Together - K&F Concept Linear Polarizing Film A4 Polarized Film Sheets Optical 20x30cm for Screen Educational Physics - Selens Polarizing Film 2 PCS 7.8x11.8 inches Adhesive Polarized Sheets Linear Polarizing Photography Filter for LCD Screen Repairing & Physics Education --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/530949784-k-and-f-concept-linear-polarization-sheet-adhesive-300-200mm](https://www.desertcart.co/products/530949784-k-and-f-concept-linear-polarization-sheet-adhesive-300-200mm) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-09-07*
