The first one is to wrap the ring with a red line. First, fold a pair of red lines into a U-shape and pull one end to make them longer. Then hold the ring with your left and right thumb and forefinger, and press the U-shaped line between the ring and forefinger. Winding the long end of the U-shaped wire on the ring from left to right, and winding the short end inward at the same time. At this time, the unopened end of the U-shaped wire will remain on the left side of the winding to form a buckle. After feeling that the winding range is almost the same, wind in the opposite direction (that is, from right to left). At this time, make sure that the rightmost side of the winding can pull out the short end of the front U-shaped wire. Thread the thread through the buckle from right to left, then thread it through the buckle and the thread at the shorter end exposed on the right side at the same time, and pull it in the opposite direction, so the thread will be pulled into the winding, so there is no need to tie a knot. Finally, just cut off the extra thread.

Second, if it is a movable ring, it can be reinforced with a needle tube in addition to being wound with red thread.

It is to cut off a very thin rubber tube, then put the trap ring, first put one side of the interface in, then put the other half, then put the rubber tube in the middle, and finally fix the position.

In this case, it is convenient and close-fitting, because the leather tube is plastic, transparent and soft, and it doesn't feel anything when worn on the hand, and it looks good.

Third, it is best to send it to the place where gold and silver are processed and make a simple adjustment.

Either way, it is not appropriate to stick it with tape. It will be very uncomfortable to wear.
