⚠ Currently Unavailable Bonus item with new blanket purchase Silk Cotton Size: Approximately 110 x 145cm Made in Izumiotsu I opened it to check because there were no care tags or size information. Since it's provided as a bonus item without a quality label requirement, the material (silk, silk blend, or other fibers) and size are likely not specified. Percentage tag missing, unknown: According to the Quality Labeling Act, non-sale items and free gifts (bonus items) are not always required to have tags or percentage displays, so they may be omitted. It's equivalent in size to a "half blanket" or "lap blanket" from Mitsui Mohi. It's larger than those sizes, according to my amateur measurements. Regardless of whether the silk content is 10%, 50%, or 100% (of the purchased item), the washing method is the same. Lower silk content is easier to handle, while higher silk content prioritizes feel but requires careful handling. If it's a conventional fabric, I assume it's either 10% or 50% silk blend, but if it's a new prototype, there's a chance it's a "good find." It won't fit in a 60-size parcel service box even when folded in half, so I plan to ship it in a bag as is. (It arrived on the 14th, so I'll reuse the brown futon bag for shipping. If you prefer a cardboard box, I can accommodate, as the 80-size rate is the same.) If an acquaintance wants it, I might remove the listing and give it away (_ _) ✽ Because the official store is closed and it's a free gift, I tried to investigate the silk content as much as possible, but it's difficult. → If you have any concerns, please inquire during weekday business hours. I can't make time during business hours on weekdays. When I purchased items, I always contacted the manufacturer directly, not the seller.
