The invention belongs to the field of living goods and discloses a cup to achieve the purposes that use is safe, and slip is not likely to occur. According to the technical scheme, the cup mainly comprises a cup body, a base is further processed on the lower portion of the cup body and is in a sawtooth shape, the thickness of the base is not smaller than 3 mm, and a plurality of protrusions are processed on the cup body; the base is made of glass material; the height of the protrusions is not larger than 2 mm. In the use process, as the protrusions are processed on the exterior of the cup body, on one hand, heat insulation can be achieved to avoid that the hands are scalded, and on the other hand, friction force is increased; as the base is processed into the sawtooth shape, friction force between the base and a supporting face can be increased, and it is ensured that the cup is stable and does not slip. The cup is simple in design structure, low in cost and good in use effect.
