A concealed closure can look neat while leaving an unresolved construction or operation question. Review how the zip is incorporated, not only whether the front view hides it.

Identify the intended relationship
For a removable cover, show the relevant material layers and closure position. Ask the responsible sewing specialist to assess the actual combination rather than copying settings from a different material.
Inspect the complete result
Review the finished appearance and the applicable operation requirements together. A successful visual concealment does not establish every functional characteristic. Preserve the approved component and construction information so another similar-looking zip is not assumed equivalent without review.
