They are slightly larger than a quarter coin and went on easy enough. I was pleased at how many were included in the purchase. I applied them to the OUTSIDE of my window as instructed, and so far (one week in) no bird strikes.I can see the decals from the inside and outside, but it's not too bad looking. I included a pic so you can see if you see the decals too. The 15 decals (so half the package) are all over my window and are more noticeable when there's a dark object behind them (like a tree), but hard to see them when a light object is behind them (like the sky). Can you count all 15? Some are very hard to see! I do recommend this product - gotta take care of the birds! ### ⭐⭐⭐⭐⭐ Works well; easy to apply *by C***E on August 24, 2025* These worked well to alert birds and keeps them from flying into a glass sliding door. Easy to apply.A bit expensive for how many stickers in a package. ### ⭐⭐⭐⭐ Seem to be working. *by C***E on September 9, 2025* Some decals were cloudy, others more transparent but so far, no bird strikes. --- ## 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.pl/products/2646386-windowalert-modern-square-anti-collision-decal-uv-reflective-window-decal](https://www.desertcart.pl/products/2646386-windowalert-modern-square-anti-collision-decal-uv-reflective-window-decal) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
