Using your Sanrio Vivid Ring is super easy - just slip it on your finger and show off your cute Sanrio character! When it comes to taking care of it, keep it away from sharp objects to avoid scratches. If it gets dirty, you can gently wipe it with a soft, dry cloth. Remember, each blind box has a random character, so there's a chance of getting duplicates. Once you open a box, we can't take it back or exchange it, so think carefully before opening. Have fun collecting all 8 different designs!
