Review on 📚 Eureka Sharp Bunch Educational Set (836083) by Bethany Ray

Ordinary antique window hinges. They worked great for me! Very pretty, good size. They also have the names of the fish which would be great for educational purposes or they could be trimmed neatly if you'd like without spoiling the look. (Note that they only stick to glass. I've seen some testimonials from people trying to build walls to their description.) I've had no problems, but if they don't stick to windows I'd suggest wiping them down dry the glass with some rubbing alcohol and then try to glue it down. I had a job like this trying to get suction cups and things like that to stick to glass.
