A simple but effective set to build an alarm that reacts when moved. Placed in your rucksack or gym-bag it will keep thieves away! As soon as a light movement is made the alarm starts to sound.
This kit is recommended for children aged 12 years and up. We know that some children may be precocious in these areas, but may we suggest that the age recommendation is nonetheless followed. We have found time and time again over the years, that Walter Kraul takes much into consideration with their age recommendations, and they really do seem a good guideline.
Made in Germany.
