Review on 🐦 Black Bird Stickers for Glass Door Protection - Anti-Collision Window Alert Silhouettes to Prevent Bird Collisions and Save Birds (9 Silhouettes) by Eric Webbie

Reason to buy: Over the years several birds flew into the glass partition to their unfortunate deaths before we finally decided to do something about it as we hope to prevent future accidents. although only time will tell. Upon Delivery: Silhouettes are delivered in a cardboard envelope, divided into separate sheets of one to 3 birds each; just peel and stick. I know this isn't rocket science, but I was expecting some instruction (e.g. clean glass first, apply by peeling silhouette corner, press against glass, wipe, etc.), but it's up to you how best to apply . And once they're on, they can't be taken off without risk of tearing. They are available in 3 different sizes; and although they were all a little smaller than I expected, they seem to be the right size on the glass to warn the birds. The time will show. Conclusion: For the price I would recommend it and buy it again.
