Thank you for viewing! I only used it once, so the condition is very good ^_^ The mouthpiece has been thoroughly washed and disinfected. Although it's plastic, it looks authentic, is lightweight, and seems easy to use. ⚠️ Because I don't have a suitable cardboard box, I will be using a combination of boxes for packaging, so the packaging may not look the best. Please understand that I will pack it carefully to ensure the contents are not damaged.
