This is the only pen and identifier for golf balls that my husband will use. Just wish we could get the pen by itself without the stencil.

My first impression of this product was that it is a great idea, until I realized that its creator had no imagination. If he/she had gone to the next obvious level, he/she would have a created areally great idea/product. By allowing the customer to submit a personal design and have the plastic template laser-cut to match his/her design that they now apply with a Sharpie Pen, it would allow the customer to quickly produce even complicated markings instead of being forced to use a ball marking whose design is limited to the holes and lines of this single template. I know many golfers who use markings such as stars, circles, their initials, etc. In my case, I use a lightning bolt!The Identifier Golf Ball Stencil Alignment Aid I did not buy this product.

Really is easy to line up, pen supplied is as good as any. Every time I pull a new ball out before a round I whip this out and stencil in the putter line. Putter lines people! They help a lot!
