Review on 🎨 Premium 32-Pack LINGXIU Silicone Nibs Tips Cover for Apple Pencil 1st and 2nd Gen - Thin, Noiseless & Protective Case - 16 Colors - Compatible with iPad Pencil - Slim Lightweight Design by Pamela Whitworth

Depending on what you buy will determine if you want to buy them. As a digital artist, they come in handy when you need more friction. Also works with Apple Pencil. They won't last very long. If you use them continuously, they will last for several hours. I used 4-6 in a day for detailed articles. If you just want more friction when writing, this might be the case. Personally, I'm not a fan of it when I'm writing. I decided to give it a try because I didn't want the downsides that I've seen for screen protectors. Hope that helps.
