This is a set of two stickers shown in the image. When shaken, the beads inside move and make a rattling sound. How about giving these to your little brother who says, "Only my big sister gets to have fun!"? The amount of water inside varies depending on the sticker, but there's no sign of evaporation. These are made overseas, so the text isn't in Japanese, but there's no strange foreign language on the sticker part ☺︎ --- Colorful construction vehicle design sticker set, perfect for decoration with beads. - Brand: YAN XIANG - Theme: Construction Vehicles - Type: Stickers - Design: Colorful Vehicles - Quantity: Set of 2 sheets - Usage: Decoration and crafts - Size: Unknown for each sheet, but a general sticker size - Material: Plastic - Features: Bead design Thank you for looking.
