Once upon a time, in an old glass family, there was a young apprentice named John. His father and grandfather were both excellent glass craftsmen, and he was also very talented and creative.

One day, John was given the task of designing and making the perfect wine glass. The glass needs to be not only aesthetically pleasing, but also scientifically correct to bring out the best in the taste and smell of the wine, allowing the taster to appreciate the taste and texture of the wine.

John began his research and experiments, trying to combine the color, material and shape of glass to design a unique wine glass. He used a variety of different materials and tools, trial and error, each time recorded, and constantly improve and optimize the glass.

John encountered many challenges and difficulties along the way. His glasses often crack or have uneven shapes, but instead of giving up, he works even harder.

Finally, after months of hard work, John managed to create the perfect wine glass. This glass is unique in shape and light in material, which can bring out the taste and smell of the wine to the greatest extent, allowing the taster to better taste and texture of the wine.

Known as "John's Cup," it quickly became the glass of choice for tasters and wine merchants around the world. Its elegance, beauty and uniqueness make it a table rarity and one of the classics of glass craftsmanship.

Today, "John's Cup" has become one of the representatives of the glass glass, everyone can use this glass to better taste the taste and texture of wine, and also more appreciate the beauty of glass.
