The product you are reviewing is made with 100% hand workmanship. A stainless metal case is used in our product. First quality double-sided suede is used in the inner lining and bellows. The outer leather is imported and first quality. It has a 1 meter 20 cm long chain. It is under the leather on both sides. 3mm thick sponge was used. The adhesive we used is very strong and prevents the cover part from being separated from the metal case. For this reason, the lid part never separates from the metal case. When you purchase our products, they will be sent after quality control and careful packaging. We hope you have a nice day.
