09-06-2025I used these for an art craft. They were very sturdy, but required a lot of glue to get string to stick. It did the job, but was pricy for cardboard.

> 3 dayIt is for sure sturdy and it’s not thick which is what I like I needed small for journals! If you are expecting it to be big it is not for you or if you want it thick! But I love it so much !!!

> 3 dayI’ve ordered custom cut corrugated cardboard before, and the quality of this product far outshines even that. These are thin but still incredibly sturdy and hard to bend! And just as a FYI, i would NOT recommend people placing these inside envelopes or flats, since these board are so stiff that your letter will be non machinable by postal services. Since letters and flats are required to have a certain percentage of give/bend-ability, your letters may very well arrive to someone bent and at worst case destroyed. ** parcels/packages/bubble mailers are okay though **

Greater than one weekI really love these for adding to items to mail to help keep them flat. However, the last batch I ordered is very warped so its difficult to keep items completely flat.

> 3 dayThese are PERFECT for shipping cards, postcards and other items you dont want to bend. These pieces are actually sturdy and rigid, which is not always the case. They are also pretty lightweight so they dont make your package too heavy. Just what I needed and Ill be back for more.
