Hamilco White Cardstock Thick Paper - Blank Index Flash Note & Post Cards Rounded Corners with Envelopes Greeting Invitations Stationary 4 X 6" Heavy weight 80 lb Card Stock - 100 Pack

The cards are made of nice, sturdy white stock. They are not sheer or transparent. Before purchasing, I had read another review complimenting the curved corners. These corners make all the difference! The rounded corners say that these aren’t just white index cards, they’re going to be hand-crafted postcards! They come in a sturdy little cardboard box to protect from wrinkles and creases. Very pleased with my purchase.

Purchase for my 13yr old & she hasn't put it down yet. Pros; Sturdy keys & great sound for the price. Cons; I wish it had note stickers, & my kid won't put it down! Lol

I wanted to make a photo collage of team. This worked perfectly and they enjoyed see all their hard work hanging in our office.

Good quality paper stock, ran through my printer easily. The rounded edges give such a nice, finished look!

I ordered these because I thought it would be a nice step up from the typical index cards. They look great but aren't as sturdy as I expected for "card stock."

I was a bit concerned that these may be too thick for my printer, which curls the paper 180 degrees between the paper tray and the print tray. But these zipped through with no problem.

These cards are perfect for me because I like to personalize card and these are sturdy, nice stock. I used watercolor crayons on them and the cards turned out beautifully. The envelopes were good. The cards and envelopes come in a sturdy box that will last rather than something squishy where the cards get ruined/bent. This is a good product for simply writing notes or, as I did, decorating them. The envelopes are sized so that if you glued things on, there were be room to easily slide the cards into the envelopes.

These are 80 pound, 10 mil thick cards with rounded edges. I was looking for flash cards that will feed and print properly on both sides in my Brother MFC-J985DW inkjet printer. This printer specifies index card max weight of 32 pounds and thickness of 6 mil. (Photo cards are spec'd at 58 lb and 10 mil.) I know these are very conservative specs so I gave these cards a try. They feed and print perfectly from the bottom paper tray even though they take a pretty curvy path through the printer. Manually removing and re-inserting accomplished both-side printing.I also bought 5x7 cards from the same company and they too print fine when manually fed through the printer's backside manual slot. The cards are not playing card thick, about the thickness of normal index cards. Fine for my flashcards. They are nicely packaged, shrink-wrapped in a small box.

The cardstock isn't too thick (wish it was a little thicker) but still works good for what it's being used for. Wish it was a little shiney on one side but not like photo paper. Cardstock worked great with my printer as well.
