I’ve had this problem for months, and ater trying a few pens, I finally took a screw out!

Making that screwdriver pen is probably one of the coolest things I’ve ever seen, it’s molded exactly!

One tip with the pens, the plastic tube should narrow, so it shouldn’t just be a pen with one straight cylinder or else it probably won’t work (I went through 6 straight pens before trying one that narrowed).
