[H3] FAQ
Q: Why is Q19 lighter than Q18 (Rose Gold 0.9g) when they seem dimensionally similar?
A: Q19 has a slightly shallower inner channel (5.5mm vs 6mm for Q18), which reduces overall material volume, resulting in the 0.1g weight difference.
Q: Can Q19 be used on a passport cover?
A: Yes. The 19mm arm and 5.5mm inner height perfectly match standard passport cover corners. Black is a popular choice for minimalist and professional passport holders.
Q: Does the matte black finish on Q19 match across a set of four corners?
A: Yes. All XKY Framing corner protectors are produced in consistent batches. A set of four Q19 pieces will have a uniform matte black finish when applied to the same cover.
