Can the bag be cut with a knife? How is it safe?

No. The bag is protected by high quality stainless steel mesh wire, which is woven in around the whole bag. Knives, scissors, cutters etc. have no chance.

My parcel delivery service person does not understand German or English. Will he/she understand Paketsafe?

Yes. For Paketsafe, no language skills are necessary. It works intuitive. Just in case, we included for every product a sticker with a visual instrucation in pictures. But in most cases, this isn't even necessary.

What happens when a 2nd delivery service comes at the same day?

When the 1st delivery service pulls the lock, it is locked. We want to ensure that your parcels are safe. According to the largest parcel delivery services, getting several services on the same day happens in average households a lot less than expected, usually only around 2-3 times a year. Households shopping a lot more than average or customers with a small business at home can either give the delivery service they trust most one of the 4 keys or often buy two Paketsafe.
