I purchased this during my student days, but I'm selling it now that I've graduated and no longer use it. I used it about 3 times for practical training at school. The cheek mucosa model was dried each time after use before being stored, but there is some discoloration (see image 5). This does not affect its use. It comes with a large carrying pouch (see image 4) and bubble wrap for protection. Dentistry, dental hygienist, practical training, model, jaw model, simple mannequin, cheek mucosa model
