This is 400g of Kurose Pet Food's 4-grain blend for small birds. The expiration date is June 2026. I have some unopened stock, so I'd be happy to pass it on to someone who has a pet bird. Since there's room in the box, I'll also include a banana-shaped waterer as a bonus. This is also unopened (please comment after purchase if you don't need it). - Product Name: 4-Grain Blend for Small Birds - Contents: 400g - Ingredients: Grains, seeds, and other ingredients - Included (Bonus): Waterer Shipping is planned via Takkyubin Compact.
