I used one mouthpiece, but I didn't use the others, so I'm selling them. *I will ship them without the box!!* I will not take the product out of the inner bag, so I will pack it without touching the straws. Straw Set for Mug S-2 These are straw parts for the Richell Aqulea Straw Mug. *The straws are the correct length for the "Odekake Straw Mug 320". If you are using them with the "Odekake Straw Mug 200", please cut them to a length of 95mm. Product Details Material: Silicone rubber Contains 2 sets (1 mouthpiece, 2 straws) Microwave, boiling, and chemical disinfection OK
