Before you commit to a side
When will my cup arrive?
Orders are handed to our fulfillment partner within 2–4 business days and arrive in 12–20 business days with tracking — we email you at every step. Limited-run stock — when a wave sells out, the next one takes longer.
Is this official merchandise?
No — and we say so proudly. Secret Cup is an independent fan-made collection with original art. Not affiliated with, endorsed by, or sponsored by any studio.
How does the color change work?
The cup is cold-activated: fill it with an iced drink and the white body turns deep crimson within seconds, the mask eyes sharpening as it shifts. It resets as the cup warms back up — no batteries, just thermochromic ink.
How do I care for it?
Hand wash only, with the dishwasher and microwave both off-limits — heat is the enemy of the color-changing ink. Treat it like the collectible it is and the transformation works indefinitely.
How does the second-cup discount work?
Add two cups and 15% comes off the second one automatically at checkout. No codes to hunt for.
What if it arrives damaged?
Email a photo to support@secretcup.co within 14 days and we reprint and reship it free. See our refund policy.
