Suitable as a Gift?
In the gift options field of the product page, we could not find any statement that noshi (gift wrapping label), packaging, or message cards are supported. On the other hand, the product description says that keyroom’s gift wrapping is available in three types, a wrapping bag, wrapping paper, and wrapping paper + noshi, through a gift ticket sold separately (source: Rakuten Ichiba product page, viewed October 13, 2026).
- Noshi: offered through the gift ticket sold separately (wrapping paper + noshi). The inscription types are not confirmed
- Packaging: a wrapping bag or wrapping paper is offered through the gift ticket sold separately. We could not find any mention of a decorative gift box
- Message cards / name printing: not confirmed
The product name includes “業務用” (commercial use), and it arrives as two 500g bags. We could not find any mention of a decorative gift box. If you are considering it as a gift, checking with the seller before purchasing how the gift ticket works and which inscription to use can help avoid misunderstandings.
