Tell us about yourself!
Might I suggest spending the money on the special screwdrivers/bits. Because not only using them over and over again but you can also open up more systems as well. Like for some examples the Sega Genesis,the original Nintendo,the Gamecube,the Super Nintendo, and a few more that I can't think of at the moment. Also you'll be reducing your environmental impact because each time your outer pen shell or plastic rod breaks some of you will just throw it away instead of recycling it.
