> 3 dayNow very warped. I live in a dry environment with low humidity so not sure why they would warp. I tried putting flat cutting board + weight on the package, but no success after 2 weeks. Very disappointing.

> 3 dayI cut about 2 inches off to fit the height of my shelves and use it to wrap quilting fabric. Its stiff enough to hold as many yards as you have. Ive wrapped 7 yards and more.

Greater than one weekI spent an alarming amount of time trying to find a cost efficient and good quality solution - this is it. I can put these in a sleeve with the art, ship them in a poly bag, and they arrive save and sound (provided USPS doesnt decide to take my fragile stickers as some dumb personal challenge).

> 3 dayGood price for what you get, just keep in mind these are very thin pieces! Still sturdy enough for little models and projects.

05-06-2025These came quick(which is fairly standard with Amazon Prime nowadays) and we’re just what I needed. I required something sturdy for packaging artwork prints and these did the job nicely.

> 3 dayWas not protected during shipping. This is not a first purchase from this seller. Last ones were much higher quality and not damaged. Not happy for the price. Only choice is to send them back Disappointed and embarrassed to use in shipments to protect precious items

> 3 dayIve brought these before but this batch was completely warped. I use for shipping books and it warps the books. Useless. edit: ordered again to see if it was just a fluke that they were warped. it wasnt. 2nd batch was warped too. probably due to how they ship them

> 3 dayThis is E-flute, thinner and stronger than common B-flute. Highly recommended for light weight and strength. I sell online and use this to protect paper ephemera, patterns, etc. Make sure the seller name is Juvale when you buy. They consistently provide good product and send it properly boxed so that the outer sheets are not damaged.
