I’ve seen so many promotional pens in my life, for sure the best range is from Bentcil in the USA, they’re nice people and extremely professional. I recommand you to visit their website if you don’t know them, these pens are really promotional pens, they communicate with the shape.
Less serious, but interesting this “painzap” pen. As the name sais, the pen zaps the pain away. I never tried it but it may work.
Not sure this pen is proposed as a promotional pen in the market yet. To visit the website of a Painzap distributor click here : Takecare
Yep, the website is in dutch, you got to learn dutch before you buy the item. Or you contact me, but of course I’ll take my usual 125% commision.
