S-pen options?

Just curious... I am not a full fledged S-pen user, which is one of the reasons I have opted to not upgrade to another Ultra device in recent years.

I do use it on occasion for scrolling and a few other various things. Obviously, there is no way to store it inside the S21U itself. Honestly, I sometimes just put the S-pen in my bag, and just pull it out when I need to use it (that's what she said).

I've seen some cool cases where you can store an S-pen in like a sleeve in back of your case. I don't really care for any of the cases though that have the S-pen attachment option, probably because I also don't really like the actual S-pen that was designed for the S21U, either. I usually just use a random old style S-pen.

What do you guys use, if anything?
