Please check the expiration date in the photos! I will ship via Yu-packet Post, either in a box of the specified size or directly in a waterproof and durable packaging bag for宅配 (home delivery). For combined purchases, the packaging size will change, so I can only accommodate orders of 5 sets or more. Thank you for your understanding! Please refrain from price negotiations! I am also selling on other sites, so items may be removed suddenly. Thank you for your understanding. #CatTreats #Churu #Inaba #MadeInJapan #GreenTeaDeodorizingIngredients
