Topps Chrome vs Sapphire

What's the difference between Topps Chrome and Topps Chrome Sapphire? Chrome is the flagship set. Sapphire takes that same 200-card checklist and makes it significantly more premium. You get lower print runs, Sapphire-exclusive parallels, two insert sets you can't pull anywhere else (Infinite Sapphire & Hidden Gems), and 4 guaranteed numbered parallels in every box. Same characters. Much tougher pulls.
