We are a relatively large advertising company. We have several chain stores in the local area, and largely business volume. The amount of materials used for adhesive vinyl is very large. Because our customers require high-end materials, the quality requirements for our materials are also very high. There have been many small problems before, but after cooperating with HEYI, not only the product quality has reached our expectations, our customers are very satisfied with us, but also the production efficiency of the company is very high, the shipment is very fast, and the service is very good. We are very happy to continue working together.
