I thought this cardstock would work for the postcards we were printing. However used with our laser printer the ink from the message bled through to the address side and it also could be easily wiped off on the message side.
My primary use is to make customized index cards. It works perfectly. Now with so many 'gift card' templates being offered online I also use the card stock to print them when sending them to my friends and family.
The paper is pretty decent for the price but only for one side. We went to four different printers with this paper. The print would be great on one side and then be faded and splotchy on the other side. We finally found a printer that could print decently on both sides. You could still see some splotchy areas. This really hurt our timeline with this job. All of the printing was with laser printers so I cannot comment on inkjet quality. I think that this can make due in a pinch but I will not be purchasing this again.
