Problems · low risk
When one press-on fails repeatedly, the pattern can point to that nail's fit, curve, edge contact, or repeated use rather than a whole-set problem.
First thing to check: Compare that press-on with its natural nail from side to side and notice whether it is narrower, wider, flatter, or more curved than the nail.
Stop here. You learned something useful about the pattern.
Try the next variable, rather than changing fit, adhesive, and routine at once.
A file can be a tool for a small fit adjustment; it is not a reason to aggressively reshape the natural nail.
Record whether the same finger and same edge fail again before changing other variables.
problem
Press-ons can come off quickly when fit, preparation, adhesive choice, or everyday contact is not working together as you expected.
problem
A cuticle-side lift can be a fit, placement, preparation, or adhesive-contact pattern rather than proof that one product is universally wrong.
tool
Fit is an information-gathering step. Compare the natural nail width, sidewall contact, curve, and cuticle area before deciding an adhesive is the issue.
difference
Glue and adhesive tabs are different press-on attachment formats with different application, removal, and reuse tradeoffs. Neither promises a fixed wear duration.
