This is a reusable adhesive I begged my parents to buy for me in France about 30 years ago. Originally, it was meant to be used as shown in the picture, but at the time I didn't know it was an adhesive and played with it like a kneaded eraser. It feels like a light clay with adhesive properties. I tried kneading one stick and it worked fine, so I'm putting the remaining six sticks up for sale. This is a great item for those interested in German-made adhesives or those who like kneaded erasers.
