Using these Sanrio Pastel Ring Blind Box rings is super easy! Just take the ring out of the box and put it on your finger. It's a great accessory for everyday wear or to show off your love for Sanrio. When it comes to maintenance, you can simply wipe the ring with a soft, dry cloth to keep it looking nice. Remember, each box has a random character. Since some designs are rare, it might take a while to collect them all. Also, once you open a box, we can't accept returns or exchanges because we don't know which design is inside. So, have fun opening the boxes and see what cute Sanrio character you'll get!
