These are samples I received when I made a purchase on Rakuten the other day. The expiration dates are as follows: Shampoo & Treatment → April 2027 Shampoo (set of 4) → May 2027 Body Soap & Lotion → May 2027 I will package them in an OPP bag and wrap them in bubble wrap to prevent any leakage. ☆ I have a cat. I will take the utmost care in packaging, but please refrain from purchasing if you are sensitive to cat hair or have allergies, as there is a possibility of hair contamination. Please feel free to ask if you have any other questions. ❀
