Thank you for the feedback! We're sorry to hear the back of your holder has a slight curve that's keeping some magnets from fully contacting the surface. Since it's a lightweight mesh design, minor manufacturing variances can occasionally affect flatness. Good news is it's still holding securely for now, but if it becomes loose over time, adding a strip of extra-strength adhesive magnetic tape to the back can help keep full contact. We'd also love to have our team look into this with you directly if it worsens — feel free to reach out to customer service. Thanks for choosing our organizer!
