Review on Grafix Medium Weight 8.5 x 11” White Chipboard Sheets, Pack of 25 - Acid-Free 0.05” for Three-Dimensional Embellishments on Cards, Papercrafts, Mixed Media, Home Décor - 25 Count by Kristen Reid

I bought a pack of this white chipboard about a month ago and it was perfect. I didn't rate it but if I did it would be a 5 star rating. So this time I ordered 2 packs and was very disappointed with the poor quality. I had to check my account to make sure it was the same seller that I ordered the first time. I need the exact dimensions of 8.5 x 11 inches for the laptops I make, no room for error. The first batch of chipboard I ordered was perfect, but the second batch was 1) not 8.5" x 11", about 1/16 inch less than 8.5. The 1st batch had the edges cut perfectly, the second batch had the edges rough.
