Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: OP-01, belonging to category: Oil Bottle Stopper

### Response:
The elegant hydraulic vacuum oil bottle stopper allows for drip-free pouring and also protects the oil from oxidation. The stopper can be firmly fitted on the neck of the oil bottle. As soon as the bottle is closed, the hydraulic pressure generates a vacuum in the bottle. To release the pressure, the upper part of the stopper is opened so that the oil can drain through the flow control valve.
