Master Series Dark Invader 金屬與矽膠小型肛門栓

The dual texture is perfect—the silicone base keeps it comfortable while the metal interior gives it that satisfying heavy feel. I love how the weight makes it stay put once inserted.

I was surprised by how solid it feels once inserted—the metal core gives it a satisfying weight that silicone alone just can't match. The small size is perfect for warming up, and the smooth surface made insertion easy. Definitely worth it for the unique sensation.

The silicone base sits flush and stable, which I appreciated during use, and the metal-to-silicone transition is smooth with no rough edges. That weight is unmistakable once it's in—definitely not for beginners, but the small size makes it manageable.
