This container is very discreet. It came with a neck chain, but really not long enough for a man to wear comfortably. As you can see in the second photo , the container is less than 1" long and has a nice sized jumpring attached to slip on a keyring/chain. Before I purchase items, I read reviews, noting one reviewer state there was black residue inside container. As a precautionary measure, I twisted a corner of a Lysol wipe and swabbed both ends. The first picture shows the residue that was removed from inside. NOT A BIG DEAL! I wash my produce beforehand. This Demood container should be ready to use.  Thank you
