MagMag Pigeon Breastfeeding Attachment | Hamu Hamu Straw Parts Only

I purchased the straw set for Pigeon's Magmag, but since my baby is not yet at the age to use the Ham Ham Straw parts, I am selling them.
Please note that this listing is only for the mouthpiece at the top, and does not include the straw, weight, or other parts.
How about using this as a spare or replacement?

The packaging shown in the photos is also not included.
The item will be shipped crushed to minimize impact on the product.
