The proof wall

Fresh off Hollis's easel

Ten real props generated from this studio's prompts. No retouching, no cherry picking. Notice how every one keeps the same line weight and lighting: that is what makes a case look professionally made.

Pre-loaded

A researched idea library, done for you

Hollis ships with a whole library of ideas, each one researched against what printable mystery case buyers actually search for. Here is a small taste. Press once and any of them becomes a full case.
