Thermo Case – Colour-Changing iPhone Case for 11 to 17 & Air

Your case changes colour the moment you touch it. Body heat flips the thermochromic pigment, so your handprint stays visible for a few seconds before the case fades back to its base tone. Every time you pick it up, all day.

Why this case

• Reacts to body heat — the shift starts around 30 °C, which is just holding it normally.
• Protection that stays slim — raised lip around the camera and screen, so neither touches the table.
• Grippy, not slippery — matte finish that doesn't collect fingerprints.
• Cut to fit — precise openings for buttons, charging port and speakers.
• Wireless charging works — no need to take the case off.

Material & care

Hard PC outer shell with a thermochromic coating and a soft inner frame. Wipe clean with a slightly damp cloth. Don't use solvents — they react with the pigment.

Common questions

Does the colour change wear out?
The pigment stays active for the normal life of the case. Constant direct sunlight will weaken the effect over time.

Does it still change outdoors in winter?
In the cold it holds its darker base colour — which actually makes the contrast stronger when you touch it.
