This is commonly known as artcard.  Being thicker, it is much tougher and is used to make covers of booklets, posters, and namecards. 
 
Like it's artpaper counterpart, this card is coated and will project printed colours well to give your documents and artwork that professional look using your very own laser printer.
 
Being in the design and print production industry for a long time, we recommend this paper for those who own a laser printer and seek to print their own collaterals like flyers, brochures, and booklets.  You can print on both sides and will work for monochrome or colour laser printers.
 
This paper is fantastic for students, entrepreneurs, and executives who need great laser quality print output in manageable quantities.
 
Example of use:
A4 size two-sided documents, flyers or posters
