Meet the 12 oz camping mug that's as practical as it is playful—a thoughtful gift for the sister-in-law who’s always by your partner’s side. It proudly reads "They Call Me Sister-in-law Because Partner In Crime Makes Me Sound Like A Bad Influence" on a sturdy stainless steel body with an enamel finish, built for outdoor adventures and everyday coffee moments.

  • Size & Capacity: 12 oz capacity, a balanced portion for campfire coffee or desk top sips.
  • Material & Finish: Durable stainless steel with an enamel coating that resists fading and stands up to outdoor use.
  • Permanent Printing: The quote is printed to stay legible through many washes and years of use.
  • Care & Maintenance: Hand wash recommended to preserve enamel finish and print quality over time.

With its rugged build and enduring print, this mug handles dusty trails and busy days alike, turning morning coffee into a moment of connection. The 12 oz size keeps portions manageable whether you’re sipping by the campfire or at your desk, while the enamel coating adds a classic look and extra durability. The permanent print ensures the distinctive message remains readable year after year, making it a memorable keepsake that celebrates your sister-in-law’s personality and your shared moments—perfect for gifting at Christmas or as a spontaneous thank-you that strengthens family ties.
