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.
