後庭配件 小巧款 - 槍金屬色搭配彩虹寶石 - 槍金屬色 6 公分金屬後庭塞，附彩虹圓形寶石底座 - NSN-0966-39

The rainbow gem base is really pretty, and the lightweight aluminum makes it easy to handle for a beginner like me. That said, the 6 cm size feels a bit smaller than I expected once it's in, and the chrome finish can make it slippery to grip at first. It does the job, but it's not mind-blowing.
