Suitable as a Gift?
The product description mainly presents it for lunch boxes, dinners, and stocking up, or for commercial use at restaurants, and we could not find any guidance on gift useSource: product description. If you are considering it as a gift, checking the following points before buying will help avoid misunderstandings.
- Please check the purchase page for noshi and wrapping options
- Since it arrives frozen, whether you can specify a delivery date and time the recipient can receive it
- Even the smallest option of 10 patties comes to 1.5kg, so whether the recipient has room in their freezer

Many posts also mention buying it together with other products from the same shop, such as meat for dogs. In addition, posts from around 2013 to 2016 describe buying smaller quantities such as 2 or 5 patties, so some posts may date from a period with a different lineup from the current one, which starts at 10 patties.
