Is this puzzle box suitable for kids?

keebox yellow is suitable for kids starting at the age of 12 as well as adults of all ages.

However, it is our most difficult puzzle box to date and can be a challenge even for experienced puzzle solvers.

We do not recommend keebox yellow for kids with little or no prior puzzle box experience.

What exactly is the material “PLA”?

Polylactic Acid (PLA) is a biodegradable thermoplastic polyester made from renewable resources such as corn starch, sugarcane, or cassava. It is a popular eco-friendly bioplastic widely used in 3D printing, food packaging and medical devices.

Properties: PLA has high strength and stiffness similar to traditional plastics such as polystyrene or PET. However it has lower heat resistance and should not be exposed to temperatures above 40°C / 104°F, as it may soften or warp (for example inside cars or when exposed to direct sunlight).

Environmental impact: PLA is industrially compostable and can break down into natural elements within approximately 12 weeks under industrial composting conditions.

Limitations: PLA requires specific industrial composting facilities and cannot be recycled in standard household recycling programs.
