This is the one I have via Amazon UK
Slim Protection Design
amzn.eu
As said it is quite slippery IMO but as someone said above, it may get tackier the longer you use it...
Issue for me is that I want grip from the off, that's why I bought the Otterbox case. Even with the clear magsafe back, the outer sides etc of the case are super grippy
More grippy than my UAG and Nomad cases are, but not by a huge amount... Noticeable though!
Spigen cases tend to be very well made though. I've used them for years now and never had any issues
The Slim Armor Pro case on my Pixel Fold is built like a tank, exactly what I wanted plus the spine protection 👌🏼
