I used it once for practice, but I couldn't use it well, so I washed it and stored it afterwards. * The silicone part has some marks as if it was rubbed with teeth? * There are also scratches on the opening of the cap from storage. Please consider this before purchasing. It's a gentle pastel green color that's easy to use for both men and women♪ During the 150 yen shipping campaign, we will ship via Rakuraku Mercari. After that, it will be shipped via Yuuyu Mercari. Thank you. First cup Adapter Mouthpiece
