NS Novelties クリスタルデザイアーズ ジュエル ガラスプラグ（キラキラストーン付き）

The sparkle from the embedded glitter stone catches the light beautifully during use, and the borosilicate glass warms up quickly to body temperature. I appreciate how easy it is to clean compared to other materials. Definitely adds a fun, glamorous feel to the experience.

The glass is surprisingly smooth and has just the right weight to it — the glitter inside really catches the light beautifully. I was a bit nervous about temperature at first, but a quick warm rinse made it feel incredible.

The glitter is actually embedded inside the glass, not just painted on, so it stays put. It’s a nice weight and the shape works well, though I wish the base were just a tiny bit wider for extra security.
