We've updated our case series names. Edge (formerly Ultra-Slim), Cairn (formerly ProGuard), and Summa (formerly UltraGuard) now reflect the experience, not just the specs. Edge: slim, light, and sharp along the climb. Cairn: firm and dependable, like stone markers that guide the way. Summa: the peak, where protection and hand-feel come together.

A. Essentially, 600D aramid fiber is a thinner thread, whereas 1500D aramid fiber is a thicker thread. The 600D version will feel more delicate to the touch and the case is slightly thinner.

Material Colors: The yellow yarns in the Lumintex^™ Edition are made from Lumintex^™ fiber, while the Standard Edition uses aramid fiber.

The glowing part of the case is made from Lumintex^™ fiber, a luminous material that can absorb energy when exposed to a bright light source, and then emit a soft glow in the dark.

Avoid prolonged exposure of the luminous area to high-energy UV lamps (≥15W) for more than 3 minutes.
Do not store the case in environments exceeding 80°C for more than 3 months.

The glow can last up to 20 minutes, depending on the intensity of the light source and how long the case was exposed to the light. Please note that the brightness will gradually decrease over time.

Too strong a magnetic force may have a negative impact on the charging speed. We have fine-tuned the magnetic force of the new phone case to ensure that it provides safe magnetic force while ensuring charging efficiency.

We wanted to provide users with a more three-dimensional tactile experience with the "StarPeak" phone case. To achieve this, we incorporated a technique known as jacquard weaving into the Fusion Weaving process. This technique involves weaving patterns by interlocking warp and weft threads to create a textured and raised design.

Jacquard weaving itself has the characteristic of being different on the front and back. The front features a woven pattern texture, while the back consists of interwoven threads. What appears to be a single-layer effect is actually the result of two layers of aramid fibers intertwining. Due to the presence of multiple layers of aramid fiber in certain areas, a textured pattern is formed when the phone case is molded (similar to how patterns in knitted sweaters may appear raised). This is a trace of our craftsmanship, reflecting the weaving process and adding to the handmade charm.

The irregular pattern signifies a more complex weaving process, which requires additional manual craftsmanship. If you are concerned about the traces of handwork, think carefully before buying.
