Do I need a leather travel jewelry case?

No — most reviewers we read recommend fabric rolls for everyday travel because they're lighter and cheaper to replace. Leather cases are worth it primarily if you want something that looks presentable on a hotel nightstand, resists scuffs over years of use, and has structured ring rolls and a mirror. Expect to pay $30 and up for entry-level leather and well over $150 for premium brands like TUMI.
