Suitable as a Gift?
We could not confirm on the product page whether noshi, wrapping or message cards are supported, and all of these are not confirmed. We also found no gift-oriented description. It is a frozen delivery item, and the page says delivery to areas where frozen delivery is not available is not accepted. If you are considering it as a gift, checking the following points with the seller before buying makes a mix-up less likely (Source: Rakuten Ichiba product page, viewed October 13, 2026).
- Whether noshi, wrapping and message cards are supported (could not be confirmed on the product page)
- Whether the recipient is in an area that can receive frozen delivery (the page says orders cannot be placed for areas without frozen delivery)
- Whether you can specify a date and time the recipient can receive it (not stated on the product page)
Among the reviews we read, 2 posts (2011 and 2012) mentioned that it came wrapped without a box, and 1 post (2010) said it was given as a birthday present. All of these are old posts and may not reflect the current packaging (Source: Rakuten customer reviews, viewed October 13, 2026).
