Comes with a Flat Head and Phillips screwdriver & bottle opener, a flashlight with zoom function and STROBE for self defense (replaceable battery), whistle and an emergency escape tool for breaking glass.

This military-grade technical pen has built-in tools the average person needs for but are nowhere to be found when they are needed the most. We took the statistics, materialized them into one item, and the result is Tac Pen by Bell+Howell. REPLACEALBE INK and BATTERIES. Tac Pens Battery and ink are both replaceable. So say goodbye to those other products that are good only until the built-in battery loses power or the after the ink runs dry. Please refer to images for break down of components.
