MagSafe Clear Case compatibility for iPhone 15 Pro Max

Apple Magsafe Clear Case - how can I confirm which Apple iPhone it is compatible with?

I have an Apple iPhone 15 Pro Max ... and I want to confirm that the case I have (that was removed when I upgraded) is the right case (as I have a few). There is no reference to the phone model on the clear case but there is a number: HKNJD3EG1GH.

I have trawled the 'Interweb' but nothing is coming up? Can anyone help please? (I want to avoid just trying it on the phone in case I scratch it ... but that may be my only option as I am pretty confident it's the correct case).

Many thanks
