You would use a variation listing since the items are all Trumpet Mouthpieces.
To make a variation listing you will need to use the Seller Hub selling manager and not the My eBay selling manager to make a variation listing ( https://www.ebay.com/sh/ovw ).
Then on the new Unified listing form ( https://www.ebay.com/sl/prelist/suggest?sr=shstart ) the Variation section is shown just after the Item Specifics section. If you do not see the Variation section then it needs to be turned on. At the top of the screen you will see three dots on the right side of the screen. Click on these and it will open a window with Settings as an available option. When you click on this you will be able to turn the Variation section on.
Keep in mind that not all categories will allow variation listings and a variation listing can only be made on a brand new Buy it Now listing and cannot be done by a revision of an existing listing or made by using one of the apps or the Quick Listing form.
