Rifle replica pen.  Silencer/suppressor comes off.  Barrel comes off.  If you take both off, it is just like a normal pen.
You may be able to find them somewhere else, but you will wait weeks for them to be delivered, or weeks for them to ship them.  Either way, if you want them to go in the hands of the post office asap, purchase from me.  I typically ship every day unless you see that my shop is on vacation mode.
There may be multiple pens in the pic.  Each quantity is for one pen only.  So if you pick a quantity of 3, you will receive 3 pens.
