We used it for making temporary sale signs for the plant nursery but it hasn't held up to rain or sprinklers very well. It was an experiment because we wanted something that was colorful and would catch the eye but needed something durable when wet too. It's not the qualify of the product that didn't work but the application.
I use this product to make my own cards and it works wonderfully. Whether I'm printing something from my printer onto it or using my rubber stamps. It is great and the price is very reasonable too.
I use the card stock for tent cards. I am a Realtor and use it to point out benefits of owning the home. Thicker than paper and can stay up for months rather than weeks at a time.
