The credit card size thin box can be made of paper, wood, cardboard, plastic metal or foam. The interior of the box can be sealed in order to take liquids or covered with reliefs for retaining pills, sachets or contact lenses. The box is opened by freeing one half (T) from the other part (B) which are joined by a magnet (M) located in the perimeter (H). The box is locked by means of a bevel or other mechanism. Opening is effected by three fingers on one hand, applied simultaneously on three points (P). Closing only requires a light force exerted on the perimeter of one half (T).
