5 out of 5 starsThe window decals arrived quickly, and I was delighted to find a few extras included. What a surprise! They make pretty light prisms in our room and reduce bird collisions.

5 out of 5 starsI am very happy with the window clings. I have purchased the rings, the circles and stars. I love the way they look. I have them on 3 windows and have ordered more. There have been no bird collisions on those windows. I almost forgot...the colors from the prism affect is beautiful!

Frequently asked questions
Custom and personalized orders
We are happy to create a custom design for you. We can pretty much create anything as long as it fits on a 12"x 24" sheet.
Can I apply these to the insides of the window? I can't reach the outsides.
You can certainly put them on the insides of the windows, they bring rainbows in the sunshine no matter which side of the window they are on. They do work better at warning off birds if they are on the outside. But they will help a little even on the inside. You also might find that your kids have fun moving them around on the insides of their bedroom windows
How do they stick?
Static cling makes them stick. When applying them, we find that a very clean window works best. If it is very cold out I warm up the clings in hot water to soften them before applying.
There is paint over-spray "dust" on my windows, what do I do?
I have had to razor-blade paint flecks off windows before to make the clings stick perfectly. Don't worry, a razor will not scratch glass, just rinse any actual dirt off first.
