CIO has launched the Mate Flat Spiral Cable CtoC 1m, a new USB-C cable that combines a thin flat profile with spiral-shaped storage, on November 21, 2025, priced at 1,980 yen including tax[1]. The cable retains a usable 1 meter length while collapsing to roughly 7 mm in thickness when stored, and supports USB Power Delivery up to 240 W. On the same day, CIO also added a new clear color variant to its popular Spiral Silicone Cable lineup, further expanding the company's tangle-free cable family.
A New Idea: A Flat Cable Coiled into a Spiral
The Mate Flat Spiral Cable CtoC 1m is a USB-C cable built around a thin flat conductor that coils into a spiral shape, balancing storage efficiency with everyday handling[1]. Magnets embedded in the cable pull it into a neat circular coil, compressing its overall thickness in storage to roughly 7 mm. The combination of a practical 1 meter run and a footprint that fits into the spare gaps of a bag or pouch is the cable's headline feature.
The outer jacket uses nylon for a soft yet durable feel[1]. The cable resists tangling when stored alongside notebooks, paperwork, or a smartphone, which reduces the daily friction of managing cables on the go. In use, the cable stretches straight when pulled and naturally returns to its spiral shape when released, an experience that meaningfully updates the feel of cable storage.
The color lineup spans six options: Light Black, Natural White, Moss Green, Shell Pink, Calm Blue, and Airy Purple, giving users a range to match a fashion sense or a desk setup[1].
240 W PD Headroom for Laptops
On the performance side, the cable supports up to 240 W of USB Power Delivery[1]. Beyond fast-charging smartphones and wireless earbuds, that headroom covers higher-draw devices such as laptops and mirrorless cameras, making it a reasonable single-cable solution for users who want to consolidate their on-the-go charging stack.
Data transfer follows the USB 2.0 specification, with a maximum of 480 Mbps[1]. The bandwidth is not designed for transferring large video files at high speed, but it covers everyday phone-to-laptop photo and video transfers and remains practical as a secondary cable that combines occasional data work with charging duties.
A 1 m run, roughly 7 mm storage thickness, and 240 W PD support is a balance that fits well with the higher-power USB-C chargers and laptops appearing on the market, and reflects the kind of practical trade-offs CIO tends to deliver.
Spiral Silicone Cable Gets a Clear Color
Released the same day, the Spiral Silicone Cable Clear Color CtoC 1m is a new color variant that joins the existing spiral-structured silicone cable lineup[1]. A transparent silicone outer layer gives the cable a smooth, hand-friendly feel that warms up to the user over time. The price is 2,180 yen including tax, positioned as an alternative line alongside the Flat Spiral Cable[1].
The clear silicone jacket is more than a styling choice: it also resists curl memory and shows dirt less obviously than other silicone finishes, addressing two common pain points with this kind of cable[1]. Performance matches the Flat Spiral Cable, supporting USB PD up to 240 W and data transfer up to 480 Mbps under USB 2.0.
The clear color variant ships in the same six colors as the Flat Spiral Cable: Light Black, Natural White, Moss Green, Shell Pink, Calm Blue, and Airy Purple[1]. Users who prefer the silicone touch can choose the Clear Color line, while those who prioritize a thinner storage profile can pick the Flat Spiral Cable, giving the lineup a clear split based on how the cable will be used.
Pricing and Availability
The Mate Flat Spiral Cable CtoC 1m carries a suggested retail price of 1,980 yen including tax, while the Spiral Silicone Cable Clear Color CtoC 1m is priced at 2,180 yen including tax[1]. Both products went on sale on November 21, 2025, through Amazon, select consumer electronics retailers, and CIO's direct stores, including CIO STORE. The Amazon ASINs are B0FXKDCLDH for the Flat Spiral Cable and B0FTZ6SZPV for the Spiral Silicone Cable Clear Color[1].
CIO also lined up sale pricing for Amazon Black Friday alongside the launch. The Flat Spiral Cable was offered at a sale price of 1,680 yen, and the Spiral Silicone Cable Clear Color at a Prime-exclusive price of 1,780 yen[1]. For a 240 W USB-C cable that pairs design polish with manageable handling, the roughly 2,000 yen price band is approachable for users picking up a secondary cable or a daily carry.
Summary
CIO's Mate Flat Spiral Cable CtoC 1m combines a thin flat conductor with spiral-shaped storage, packing a 1 meter cable into roughly 7 mm of thickness when stowed. It supports USB PD up to 240 W and 480 Mbps data transfer under USB 2.0, all at 1,980 yen including tax, a reasonable price for a single cable in this class. The simultaneously launched Spiral Silicone Cable Clear Color CtoC 1m comes in at 2,180 yen including tax, adding a clear silicone design that leans on the material's texture. For users who want a cable that does not tangle in a bag, or who care about how their desk and gadget pouch look, the two cables are worth a serious look.
