cup's specialty: 1. The cup and the cup cover, other than the water exit and air intake, are completely identical to all existing cups in the market from material and structure.
2. The current one-time use cups in the market have a common usage problem and that is there is likelihood of leakage at the connection of the cover and the cup. However, this cup of ours will definitely not leak at all.
3. Drinking from this cup offers a smooth and even stream of liquid with no inconvenience or obstacles.
4. The cost of the cups is as cheap as other regular cups, including the total price for the lids with fully functional straw, rubber air intake hole, rubber suction tip and self-adhesive tape.
