I am incredibly impressed with the FR-4 protective sheeting I recently purchased from Beijing Shine Universe Science And Technology Company. The product's quality is outstanding and exactly what I needed for my project. What truly made this a five-star experience, however, was the exceptional customer service from Cardo. She was my main point of contact and was so professional and helpful throughout the entire process. Cardo made ordering simple and straightforward, and she provided consistent updates on the shipment's progress, which gave me great peace of mind. Her proactive communication and attention to detail made the entire transaction seamless. I highly recommend both this company and their products. It was a pleasure doing business with them, and Cardo's assistance was invaluable. I look forward to using their services for future purchases.

shape and size is great but the only thing I don’t like is the non-slip grit ! its not very good quality, it needs to be smaller like sand with a semi gloss paint finish this one is more glossy and more slippery
