Mr. Li from Zhejiang Garment Factory had previously developed a voltage mark with small letters in other factories. However, when he was about to make the goods, the size of the letter lines of the large goods provided by the supplier was different from the sample, and the lines of the large goods were obviously much thicker. Later, he found many factories to redevelop but none of them worked. Either the effect was not good or the glue was not firmly fixed and easy to fall off. Mr. Li was also very anxious when the delivery date was approaching. Later, he found our company through the recommendation of a friend. Our company expeditiously processed the sample in 2 days. After the sample was confirmed, more than 10,000 large goods of Mr. Li were delivered within a week.
