Using these handlebar grips is straightforward. First, clean the handlebars to ensure a smooth surface. Then, apply some rubbing alcohol on the inside of the grips and the handlebars. Slide the grips onto the handlebars and wait for the alcohol to dry. When you want to remove them, just apply rubbing alcohol again, and they'll come off easily. As for care, keep them away from sharp objects to prevent cuts. You can clean them with mild soap and water to keep them looking new. Also, don't expose them to extreme heat for a long time, as it might affect the silicone's properties.
