50-Pack Large Corrugated Cardboard Sheets for Mailers, 11x14 Flat Packaging Inserts Pads, Shipping, Packing, Mailing, Dividers, Crafts, DIY Art Projects Supplies (2mm Thick)

Was 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

Ive ordered thousands of sheets of cardboard from Juvale. These are my favorite because they are E flute and are sturdy and strong. They work great for making poly mailers rigid. Unfortunately, over the past few months Ive noticed that EVERY pack is warped. That makes it extremely challenging to use them for mailers. No matter how much weight I put on them, they will not straighten. I will be finding another supplier if this issue isnt corrected.

Price is a little high for cardboard

A lot of them are bowed, and I cannot get them to be flat. The pieces that are flat feel very sturdy and great for shipping sheet music. The box it came in was ok, so Im not sure what happened. If they were all completely flat, itd be perfect.

The fit is perfect, the insert is firm and will do what I intended them to do.

Just what I needed to sell prints of artwork. These + plastic sleeves are perfect for customers to pick up an item and carry it without worry it will bend.

This 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.

Thin, but a little thicker than card stock. Not really flimsy. A nice insert stiffener for semi-rigid mailers. Would use a little thicker pad for more protection.

Just what I needed. They are sturdy and easy to work with A great price

This product was perfect for the purpose I intended. The cardboard was not too thick so could be cut with scissors to make crafts.
