A nasal support device (110, 34, 40) includes a device body (42). The device body (42) defines a perimeter shape of the nasal support device (110, 34, 40) and also can include a nasal support structure (62). The nasal support device (110, 34, 40) also includes adhesive (44, 66) carried with the device body (42). The nasal support device (110, 34, 40) further includes a peelable backing (46) that covers the adhesive (44, 66) and includes at least one peelable backing (46) piece that is divided into a first section and a second section by a pre-defined fold location (206, 86). The pre-defined fold location (206, 86) is configured such that the first and second sections of the peelable backing (46) piece remain coupled together at the pre-defined fold location (206, 86) after folding at the pre-defined fold location (206, 86).
