I cannot believe how fast this got to my house! The pencils work great!

Must sharpen very slowly w/ elec. sharpener!

Gets the job done marking layouts on bowling balls.

Extremely fast delivery.

I used to be one of those guys who only cared about pin up or pin down drillings. I didn't care about Pin to PAP distances or drill angles at all. I just wanted my Pin and Mass Bias in certain locations and that was it. My ball drillers followed my drilling requests and that was final. LOL. But since then, I have become more aware of how to layout a bowling ball and how dual angle drilling layouts really work. Unfortunately, I had no clue on how my old balls were drilled in relation to my PAP, and I wanted to find out my specs. Fast! So, after purchasing a Pro Sect at an extremely discounted price, I needed some marker pencils. I went to a local craft store and bought a white chalk pencil thinking that it would do the same job. Wrong! It was a waste of money. LOL. Afterwards, I remembered that you could buy these marking pencils online for less than what the craft store was charging, and found out that they work just like the ones in the pro shops. They work just fine, and they are easy to sharpen and clean up from the balls. Now, I can confidently find any dual angle layout on any ball and mark lines and numbers without any issues. I can also layout a ball before I even get to the pro shop if I decide to buy another ball online. If you are in the market for good ball marking pencils, look no further. These are great. Peace!

Very easy to see the ball marking and its very bright. outstanding to use
