Exactly what I expected. Good Product

Make sure you get the right size.
I thought I had ordered the correct size after using several measuring processes. However, damn it did not work. The good news. I am using these for another project I have going on so they will not go to waist. The quality is great and the blue sets off the bottles I am using them in.
