To answer that feedback, we created this optional slit so you can enjoy the heartbeat glow even with the Metal Gauge Kit installed.
If you prefer a stronger, uninterrupted metal look, choose the kit without this option.
If you want to keep enjoying the KODO glow, please select this option when ordering.
By using our separately sold Colored Layer film, trimmed to your preferred shape as shown in the photos, you can also change only the color of the heartbeat glow area. Feel free to customise it to match your own taste.
