Measured weight is 508g, 42g below the packaging figure. Overall length is 16cm and internal length 14cm. The packaging states manufacture in China. Material is rated +1 on the review's own scale, with slight odour and tackiness, not standardized hardness. The regular shape is easy to grip and the sample has no obvious exterior defects. A small round entrance simplifies detail.

The front 1/2 uses transverse and zigzag friction texture; the rear 1/2 has coarser compression elements. A centred channel provides even wall support. Front and middle texture match the firmness reasonably well, producing clear but not excessively uncomfortable feedback in a moderate-to-high intensity direction, without a strong anatomical feel.

The friction design is more consistent than some large-cavity models in the series, but material cleanliness feels less convincing and the channel is less distinctive than 不知火. The original recommendation is 3 stars.
