Funko have announced that a set of Deadpool Pop! Pens will be arriving in stores soon. There are three different types; Deadpool in his standard red suit, as well as X-Force and Inverse Suit variants.
A new Yellow Suit variant of the 'Thumbs Up' Deadpool Pop! has also been spotted on popinabox's website. It's uncertain if this will be an exclusive in the US but we will update you when any new info arises.
If Deadpool isn't for you, then you may be more interested in the upcoming Star Wars Pop! Pens and Pins. BB-8, Kylo Ren, Captain Phasma and a Stormtrooper will be topping the pens, while C-3PO, Yoda and a Stormtrooper will be making their way to the Pop! Pins category.
