RED SILICONE PLUG

The red color makes it easy to find in a drawer, which is a nice bonus, and the silicone is smooth enough that insertion felt comfortable right away. It's held up well through a few uses and cleans off easily.

The silicone is much firmer than I expected, which actually makes it feel more secure once it’s in. Cleanup is a cinch with warm water and soap, and the red color is a fun little detail that doesn’t show up in the photos.
