The concept of free packaging supermarkets means that food can be transfered into private containers. This includes not only fruits, vegetables, rice or pasta, but also liquid foods, such as dairy products, oil or vinegar. A glass bottle/storage jar combo is used here for storaging liquid and solid food. The bottles are made in conjunction with sand creating a rough surface which is comfortable to hold. Characteristic of the basic shape is the constriction, which was derived from the Russian doll Babushka and allows a secure grip.
