We came up with this cufflinks crazy design idea from watching carpentry work being done in our storage facility a couple of days ago. Great for a carpenter or anyone in construction. Since then, we have received bulk orders from Cuff-Daddy customers most of whom are working in the field of engineering, carpentry, and architecture. Well, what's not to like about this miniature yellow colored liquid level measuring device? So, if you or someone you know hails from the angles and measurement profession, purchase a pair now and be delighted at the compliments you will surely receive for donning this trendy item. We also offer this in other colors so be sure to check on those too.
