☆Free shipping (sent via postal service - irregular shape) ☆For Hokkaido, Tohoku, Okinawa, and remote islands, we will also send via Japan Post's regular mail service. (Please note that it may take longer than usual delivery.) When bitten, it makes a "peep peep" sound, exciting your dog. They will chew on it enthusiastically. (The whistle inside is small, so it may not make a sound unless they bite the right spot.) If you throw it after it makes a "peep peep" sound, your dog will happily fetch it. Perfect for relieving lack of exercise. ⚠️ We will create a dedicated page on Mercari, so please be sure to purchase from there. ※For bulk purchases, we will ship via home delivery (Takkyubin). Therefore, we will charge an additional 200 yen for shipping. Thank you for your understanding. Inventory: 1 brown left Product number: 8-2355-0059
