Using this Melokuro My Melody Smartphone Holder is easy. First, peel off the release sticker on the back of the holder. Then, stick it firmly on your smartphone case. You can use it to hold your phone up for hands - free viewing, like when you're watching videos or having a video call. It also looks great as a cute decoration on your phone. When it comes to maintenance, just use a soft, dry cloth to wipe it clean if it gets dirty. But keep in mind, this holder doesn't work well on phones with curved or matte backs, glass - backed models, soft silicone cases, or materials like leather or cloth that are hard to stick to. And if the surface is uneven, it won't stick properly either. We suggest using it with a resin smartphone case for the best results.
