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.
