It is made of high quality, anti-slip silicone material, smooth on the outside with a corrugated-looking texture on the inside. This strong and durable material will keep its shape and cards that will not fall out. Strong elastic pouch can securely hold cards (we suggest fit 3 cards) and cash, as well as small items that can be easy to lose such as SD cards, junkdrives, earphones, keys, etc. The price includes the shipping cost to ca. QTY over 50K by ocean. Rush and sample service is available. 100% gurantee for quality. Thanks.
