The glow-in-the-dark feature in our covers is typically activated by exposure to light which charges the phosphorescent materials used in the product.<br>To optimize the glow effect please follow these steps:<br>- Charge under Direct Light: Expose the cover to direct light for an extended period preferably natural or artificial light before use. This helps the phosphorescent elements absorb energy.<br>- Limited Ambient Light: To experience the maximum glow effect use the cover in low-light or dark environments. Excessive ambient light can diminish the intensity of the glow.<br>- Recharge as Needed: If you notice a decrease in the glow intensity over time simply recharge the cover by exposing it to light again.We hope that these suggestions enhance your experience with our product and we are confident that youll enjoy the glow-in-the-dark feature after following these guidelines.<br>Once again thank you for bringing this to our attention.
