Using this arm rest is easy. First, decide whether you want the straight or curved style. Then, place it on the table where you'll be doing the nail treatments. Press the two suction cups on the bottom firmly against the table to secure it in place. Your client can then rest their arm comfortably on the soft pillow. When using, make sure the table surface is clean and dry to ensure the suction cups work well. After use, you can wipe it with a damp cloth to keep it clean. Avoid using harsh chemicals as they may damage the material. Store it in a dry and cool place when not in use.
