Silver fiber; coverage: The surface is fully covered with silver fiber, and the finger sleeve has ultra-high sensitivity everywhere. It can accurately restore your sliding every micron, every click, without mistakes, helping you break through the current bottleneck. Hand-sewn: This finger sleeve is made by hand-sewing sterling silver fiber fabric. There may be a slight difference in the appearance of each finger cap. The disadvantage is that there is a defect directly above the nail, but it does not affect the use; the advantage is that it fits the finger very well. Just like without a finger cap: The silver fiber material we use is not only ultra-thin and ultra-sensitive, but its coefficient of friction is close to the friction between the finger and the screen. Not too slippery like a textile finger sleeve. Silver fiber fabric: Finger cots made of silver fiber fabric are cooler and more comfortable than other rubber and cotton finger sleeves. Thanks to its ultra-thin thickness, you won't feel stuffy even on a hot summer day. Note ultra-thin: Excessive sweat can affect its performance, so this finger sleeve is not suitable for people with hyperhidrosis. Its elasticity is not as good as the textile finger. If your finger is thick, I suggest you buy a textile finger. The surface is covered with silver ions. After a period of use, it will be blackened by oxidation.
