Honkai: Star Rail: Phainon Color-Changing Stainless Steel Cup - Luckin.

Is it just us, or did Phainon just become the coolest desk companion? This Luckin Coffee collaboration is finally here, and it’s bringing that fresh Amphoreus energy straight to your daily routine. If you've been following the latest Trailblaze missions, you know Phainon doesn't do anything halfway—and this cup is no exception!

Visual Highlights

The design features a super-cute chibi Phainon looking as confident as ever, framed by stars and sun motifs. But here’s the best part: the color-changing magic. When you pour in a cold drink (below 5°C), the cup reacts, adding a whole new layer of visual flair to your setup. The light blue aesthetic is perfectly on-brand for our favorite silver-haired warrior.
