At a glimpse, they may look like some pretty sharp photos, but actually all those pictures are hand drawn with a humble Bic ballpoint pen! Can you believe this photorealism? Human eye can be fooled so easily!

Spanish artist Juan Francisco Casas, who’s around 33 at the time of writing this, uses up to four 14p ballpoint pens to create his stunningly realistic drawings, measuring up to 10ft (3 meters) high.

The use of penballs makes this talented artist’s drawings even more peculiar, which certainly has played a big role in his way to success.

Juan’s source of drawing ideas comes from his own photographs of nights out with his friends, and his works are already a sell-out at exhibitions. You can only imagine how wild his parties are, as half of his cool drawings include girls that forgot to put on their clothes.

So, if you really want to feel bad about your pen drawings – have a look at these 25 Incredibly Photorealistic Drawings drawn with a humble BIC PEN.
