Not exactly a Cadillac product, but looks great, lots of features, and impresses everyone who sees it.This multi tool ink pen is a strong heavy duty feeling writing instrument. All of the pieces work really well and very smooth. The little screw driver inside the pen is in very sturdy it doesn't shake or rattle at all unlike the other pens I have that are basically the same as this one. Plus the main frame of the pen seems so sturdy that I think that you can put it into a tactical pen self defense role and it would do just fine. A great multi tool and writing instrument it even includes 4 extra pen refills.The pocket holder thing scratches the colored measuring portions fairly easy which is annoying but handy tool. Makes fir a cool gift too.Update pen broke and wetting portion won't stay out una ke to write with lasted maybe 6-8 months wouldn't have called it "heavy" use maybe moderate if that.Great little gadget but this was for a gift and it came in a plastic bag.Writing and the screw driver convinced.Its kinda cool! I got it for a friend and now I want one. Its nice to have on the desk and comes in handy, a lot more than they expected.This was a present, I already have one. She is finding it's helping her game accuracy and the tool attachments are so handy. Excellent! Great quality! Oh, and a built in level.We love these pens! They have a stylus, too. Great to find the refills!
