Shaker keychains made with resin! No oil is used, so they make a rattling sound. The heart lollipop is removable! A strawberry charm has been added as an accent! Since red is the main color, it's perfect for supporting your favorite idol or character ♡ Also recommended as a gift for friends! Please note that these are handmade items, and may contain air bubbles, uneven paint, or dust. The contents inside may not shake easily depending on their size. Each item is carefully made, but they do not have the same level of perfection or durability as mass-produced products. Thank you for your understanding and purchase.
