🔋 Cold drink. Dead inside.

The Functioning™ Tumbler is your emotional support beverage container — sleek, matte, and as unbothered on the outside as you’re crumbling on the inside. Whether it’s iced coffee, sad hydration, or panic-fueled energy drinks, this 20oz stainless steel sidekick keeps your drink cold and your sarcasm visible.

  • 20oz double-wall stainless steel
  • Reusable straw + secure lid
  • Sleek matte finish, cylindrical design
  • Fits most car cup holders
  • Hand-wash only (but let’s be honest, you’re not washing it today anyway)

Take it to work, therapy, or wherever you pretend to be functioning.


Because your drink deserves better — even if you’re running on 3% battery.
