Box of 12 BIC 4 Colors multifunction Grip Pro silver pens

Revolution on the planet of 4 Color pens: the green ball, often less used than the others, has been replaced by an HB Critérium lead. 
Thanks to its push button, this all-in-one clip pen allows students and professionals to quickly choose their color and organize their note-taking while keeping their pencil case light. 
The 1.0 mm black, blue and red beads guarantee a smooth flow of ink for writing up to 2 km, while the 0.7 mm lead allows for very precise annotations. 
Need to reload the mechanical pencil? 
Easy: unscrew the body, pull out the tip and insert the leads into the tube.
