I came across another great Dollar Tree find by the company INC. mechanical colored pencils with sharpeners. Everyone has a system to mark their scores and parts. I usually use a red marking to draw attention for myself. Other people I know use different colors to represent tempo, time signatures etc. Whatever you choose to do, these are great! I don't sharpen the tips on mine. You have to take the lead out and sharpen it on the top. I just keep writing and marking with mine. I utilize the various colors for my scores and parts. I just keep them in my bag with me where ever I go. Time to mark some parts.
