Age: +5 years. The adventure set includes everything children need to explore their environment, play and communicate with friends. Thanks to the telescope, children can play at being explorers observing distant objects and the toy compass (no real functions) will be a great addition to the terrain. If they are preparing for an adventurous expedition in the dark, they will find a torch very useful, which they can also use to send secret signals. However, the biggest innovation of this set are the walkie-talkies, which allow communication up to a distance of 120 metres in a flat, open space (depending on terrain and weather conditions). Thanks to user-friendly control buttons such as ‘TALK’, a design perfect for small hands and an amazing digital sound, they are ideal for playing spy games or sharing secret information. Plus, they have detachable belt clips, so kids can clip them wherever it's most comfortable for them. To operate the torch and walkie-talkies, you'll need batteries (not included in the package). Six 1.5 V AAA/LR03 batteries for both walkie-talkies (three for each) and two 1.5 V AAA/LR03 batteries for the torch. The battery compartments can be easily opened with a screwdriver (not included). On the walkie-talkies, simply remove the clip on the back and on the torch, open the cover on the bottom.
