The nose pads are always fitting to the skin and are consumables.
There are various nose pads, but this is a silicone type nose pad.
If you want a "no-slip nose pad", then this is a silicone nose pad. It is hard to communicate to those who have not experienced silicone pads, but you will be surprised how it feels sticky to your skin.
However, the disadvantage is the silicone material that has a shorter lifespan than hard pads and absorbs sweat and water so dirt can be noticed. (In such cases, you can wash the pad with a cleaner or similar to that of this situation.) )
If your glasses are easily slammed, please consider it.
Installation is limited to a screwdriver-type pad carrier. Perhaps if your existing glasses or sunglasses are a "screw-on pad", you can install them by yourself, but if you have a one-touch or tight-fitting pad, you cannot install them before making your purchase.
