High end material for a form factor that is inherently fragile?
Not a good idea.
It's only Note if the pen goes in the phone.
@userGS8ZgxV5M2 I have had the Note 7 and Note 8. I currently have the Note 10+ and Note 20 Ultra 5G. I bought the Z Fold 3 using the Note 10+ as a trade-in. I am really liking the form factor so far. I think the S Pen case isn't the greatest solution but it works. Writing on the big screen with the S Pen is very comfortable. The S Pen is bigger than the Note S Pen and sized like a regular pencil.
The S Pen case is removable from the Z Fold 3 case so you can use the case without the big bump along the seam.
