What heat shrink is proper for this bottle? Do they come with lids or sold separately?

For this bottle, a 66 mm x 35 mm shrink band works best when paired with a 38‑400 closure, based on cap diameter and coverage guidance outlined in our https://www.tricorbraun.com/blog/shrink-bands-for-bottles-and-jars-a-sizing-guide.html. Proper shrink band sizing depends on the outer diameter of the lid and the height needed to cover the cap and neck opening. This bottle does not come with a lid, and compatible 38‑400 closures are sold separately.
