This is a dog trainer positioned for use at home. It is light on the whole, easy to wear and easy to carry. It uses a home-based design technique in its appearance design, which is different from professional and outdoor feeling, narrowing the distance between public users and products, and weakening the feeling of dog trainer. At the same time, acrylic material and back-to-back display area are used to reflect household light technology, and glue coating technology is used at the hand fitting to improve.
