Review: Bouchon parfait - Parfait, bien étrange sur la bouteille
Review: The smell of the red silicone - For those who are sensitive to smells this cap is not a good choice. It has quite a strong smell from the red silicone. I cleaned it many times and left it outside, anyway it smells.

Parfait, bien étrange sur la bouteille

### ⭐⭐⭐ The smell of the red silicone
*by M***A on 21 March 2024*

For those who are sensitive to smells this cap is not a good choice. It has quite a strong smell from the red silicone. I cleaned it many times and left it outside, anyway it smells.

### ⭐⭐⭐⭐⭐ Worth the money
*by A***N on 29 July 2025*

Love it, great attention to detail. It comes with two straws, you cut it to decide the length so it works for all bottles that fit the lid shape. The red tab at the bottom can be used to hang the cap on the side of the bottle so its easier to fill up without pulling the entire straw out.
