Item arrived on time. As such they are super cute and make my purple PS4 controller fun! Attaching the thumb grips was easy, although it took a few tries to make sure they were in place and to adjust the paws. I also like how rubbery they are so they are very easy to attach and detach to the joysticks. Of course they are nice to touch! I currently only use purple pens, but plan to use gray pens over time. The grips are also universal if you're using other controllers (the back of the box says they also work with Xbox One controllers, Nintendo Switch Pro controllers, and other full-size controllers along with PS4, so keep that in mind). . . Definitely something to buy if you're interested in customizing your controllers! It's very affordable and comes in a variety of colors! Will definitely consider buying another set in the future!
