[H3] FAQ
Q: Does the matte black finish scratch easily?
A: The black electroplated coating offers reasonable scratch resistance for normal use. For high-abrasion applications, a thin clear-coat sealant is recommended after installation.
Q: What is the difference between Q03 (1084# Yellow Gold) and Q04 (1211# Black)?
A: Both share 30x6mm dimensions and 0.2mm sheet thickness but differ in finish color. Q03 is yellow gold; Q04 is matte black, suiting different design aesthetics.
Q: Is this suitable for a leather journal?
A: Yes. The slim 0.2mm profile and flush fit make Q04 ideal for leather-bound journals where a low-profile, sleek corner guard is desired.
