It's very Christmas ... the KiddyPlugs Advent Calendar is opened. In our 22. Doors you have the chance to 1x Silenta professional hearing protection - the hearing protection for adults. How can I participate? Just write under the post of this little door whether you already have all the presents or whether you have to throw yourself into the fray one last time on Monday! You can find further conditions of participation on our Facebook page or on kinder-gehoerschutz.de! We wish you good luck.
