The center stencil is a normal size but the overall stencil is tiny. You need to know where to place it on the racquet and tape it down to ink. It is a very cheap plastic and needs to be taped down well before inking but it does work if you find a good ink. Krylon spray paint works alright.

Helps add a touch of class to your racket, but I wish the outside edge was a little bigger to help with placement, and I wish it was made from slightly sturdier material.
