Playmobil Family Fun Sunburnt Swimmer Set #70112 Beach 18 Pieces Color Changing

Here is how the effect works:
Exposure to UV Light: When the figure is exposed to direct sunlight or another source of UV (ultraviolet) light, the special ink reacts and changes color, causing the figure's skin to visibly turn red, simulating a sunburn.

Fading in the Shade: Once the figure is removed from the UV light and placed in the shade or indoors, the ink gradually becomes transparent again, and the "sunburn" fades back to the figure's normal skin tone.

This feature is designed as a fun, interactive, and educational way to teach children about the importance of sun safety and applying sunscreen, as the set comes with a miniature sunscreen tube accessory to act out sun protection scenarios. The "sunburnt" figure is meant to serve as a visual reminder of the consequences of too much sun exposure without protection.

This was purchased in Europe and has some damage to the box along with price tag residue which you could remove with a low heat blow dryer.
