I use this set on my very frequently used Apple Pencil. The cozy for the little charging cable adaptor resides on my spare cable, and gets used..uhh..never, actually. It's nice to have the sense of security that it will stay with that cable should I need it, though.

The cozy for the tip of the pencil does a good job of protecting the tip (except for the one time when I didn't have it on and dropped my pencil tip-down on concrete), but I've noticed it tends to get lost pretty often. That may be my fault, so no points taken off there.

The charging cap cozy is where it's really at, though. This thing is basically my fidget toy. Push on the silicone strand bridging the cap and the pencil together makes the magnetic cap pop off in such a satisfying way. I do this way too much. It functions exactly how it's supposed to, in case you aren't interested in it's fidgeting abilities.

I took off a star for durability because the cap protector has a small tear(?) in it, at the very top. I have no idea how this happened, but it is annoying to constantly see a small piece of silicone slightly raised above the rest because it's torn.

I don't use this outdoors much, but either way they haven't yellowed at all in my 11 months of using this product.

Would I recommend this product? Yes, I definitely would. It's great for keeping all the little pieces together, and it also add weight to the pencil so it doesn't roll or blow away. You could theoretically use it as a paperweight if you so desired, and you'd have few issues.
Would I buy it again? Yep! If I happen to get another Apple Pencil, or if someone I know gets one, I wouldn't hesitate to gift this to them. As I said before, it keeps the little parts safe, cause no one likes a missing charging cap.

The media could not be loaded. Fits my Pencil 1 Gen perfectly.
I'll have to use the cap and tip with a different set up bit over all I love it!!

Now I don't have to lose my cap

When you add anything to your pencil it will be a problem storing the pencil in almost all iPad cases with an internal storage slot for the pencil. The product itself is fine. It's storing the pencil that is the problem.

Works as advertised. Very useful overall.
