These silicone wristbands are made of 100% industrial strength polished genuine silicone, unlike the flimsier and lower-quality rubber bracelets offered by others. They are glow in the dark with neon green ink filled F.R.O.G debossed on each one. Debossed bands are popular because using this method, bands have text that will not wear off over time. F.R.O.G stands for Fully Rely On God. Price each one.
