?Warm Tips of Using Gel Pads?: When you use our soothing gel pads, please make sure that the surface of the metal pads is clean and dry. Secondly, you can take the gel pads from the transparent small bag, then carefully put them on the metal pads of the neck massager. After that, put on your neck massager with the gel pads and adjust it to fit closely to the skin. Finally, you can start massaging with the neck massager. ?Soft, Light, and Easy to Use?: Our gel pads are moderately sticky and not only stick well to the skin and the metal pads of the neck massager, but also can be easily removed, without any obvious feeling of adhesion. Thus, it's very convenient for people to use no matter at home or during travel. ?Skin-friendly Soothing Gel Pads for Neck Massager?: Our gel pads are made of eco-friendly material and suitable for most people to use. On the one hand, We use disposable vacuum packaging, a small transparent bag with 2 pieces of gel pad, which is just enough to meet the needs of one-time use. On the other hand, it can also protect the gel pads from drying out or losing adhesion to ensure that the gel pads you receive have never been opened or used. ?Gel Pads to Effectively Relieve Pain?: Our gel pads can effectively relieve sensitive skin from the discomfort of pins or needles when using the neck massagers, helping people to relax and enjoy the massage at the same time. ?Gel Pads Fit for ST-304 & Other Models Neck Massagers?: The neck massager gel pad is just the right size for the metal pad of our ST-304 neck massager. Moreover, as considerate accessories, it can be used with our ST-304 or other neck massagers to get a better massage experience.
