Mod your mug.
A food-grade stainless steel cup insert for the CHUUG V3. Drop it in, twist, done · your drink lives in steel, and your CHUUG wears a new interior. Swap the finish whenever the mood changes. Fits the V3 only.
Steel where your drink lives.
The SPINsert drops into your CHUUG V3 and twists home. From then on every sip touches food-grade stainless steel · no coatings, no linings, nothing between you and the metal. And because it lifts straight back out, the finish is yours to change: steel today, gold tomorrow, gunmetal for the weekend.
- Food-grade stainless steel, nothing to wear through
- Swap the colour, keep the mug you've broken in
- Twist-in fit · drops into any CHUUG V3, no tools
The right material.
Polished metal is a mirror for mess. Fingerprints, watermarks, smudges, all shown straight back to you. So we brush every SPINsert. The grain scatters the light and hides the handling.
Beneath it: food-grade stainless steel. No rust, no chips, no coatings to wear through. Built for decades of daily service.
- Brushed grain hides fingerprints and watermarks
- Food-grade stainless steel, corrosion-proof for life
- No plating, no lacquer, nothing to chip or peel
