The plastic cracks when it's cold outside.

[This review was collected as part of a promotion.] so happy to have this shield bag, As a designer of new homes in Michigan weather is very unpredictable, wind, snow, rain, sun all in 4 hours. Love having this in my arsenal so a little drizzle doesn't dampen a site visit !

[This review was collected as part of a promotion.] This works great for our blue prints! It’s a awesome case to carry them around in especially during the rain season here in Florida. It keeps them dry and protected when I’m running in and out of buildings.

[This review was collected as part of a promotion.] Got this for my job plans and now I can't imagine living without it. There are countless times when plans have gotten torn or wet and get completely ruined as I travel from job to job. This plan shield has eliminated that stress from my life and I will definitely be ordering more!

[This review was collected as part of a promotion.] This is a great product for transporting and protecting any form of blueprints. I use this item for various welding blueprints. My hands are always dirty one way or another and it looks very unprofessional to have dirty or torn up diagrams. I especially enjoy that I can roll this right up when I need to set it aside. The plan shield also prevents your blueprint from folding back up. Has weights on the edges to keep it open as well. Overall it’s a very helpful product to have and it does it’s job.
