Cast Clear Acrylic Sheet 1/8 Inch Thick Clear Plexiglass Sheet, Thick Clear Plastic Sheet for Crafts, Highly Transparent Plexy/Plexi Glass Sheets for DIY Display Sign Board Panel 5x7 (10, 5" x 7")

I purchased the 5 x 7 acrylic sheets for a wedding I've been hired to do, and after completing my signs. I noticed that these DO NOT fit in a acrylic holder made to fit 1/8" thick sheets. So I try different acrylic holders that I had, and guess what?... STILL wouldn't fit! 2 different holder from 2 different sellers, and these so called 1/8" sheets didn't fit! Now the best thing that will happen is I get my money back for the signs, BUT because I have already FINISHED with them! I now LOSE out on ALL my product I put into them. Paint, vinyl, printer ink, ribbon, and gold flakes!! not to mention MY TIME!
