Two new color options have joined the slim Bluetooth mouse lineup at Sanwa Direct, the direct-sales online store run by Sanwa Supply. The additions are Dark Gray (model: 400-MABT178DGY) and Light Blue (model: 400-MABT178LB), both priced at ¥2,073 (excl. tax).

Two New Colors Expand the Lineup


The mouse's rounded silhouette and smoky nuance palette already found fans in Blue Green, Gray, and Pink. The new Dark Gray (400-MABT178DGY) brings a calm, composed look, while Light Blue (400-MABT178LB) offers a fresh, airy feel. With five color options now available, there is more room to choose a shade that fits individual style or desk surroundings.
Slim and Light Enough to Take Anywhere


Weighing approximately 62.7 g and measuring just about 3.09 cm in height, the mouse slips neatly into a bag or pouch. Its flat profile suits both work desks and personal spaces, making it a practical companion for cafés, business trips, school, and daily use.
USB Type-C Charging — No Batteries Required


The mouse uses a built-in rechargeable battery charged via USB Type-C, so there is no need to keep spare batteries on hand. It also supports fast charging, bringing charge time down to approximately 50 minutes — about one-third of the previous model. Charging while in use is supported as well.
Bluetooth with 3-Device Multi-Pairing


Bluetooth connectivity allows pairing with up to three devices simultaneously. Switching between a laptop, tablet, and another computer is as simple as pressing the button on the underside of the mouse.
Quiet Clicks for Any Setting


Silent switches on both the left and right click buttons as well as the scroll wheel keep click noise to a minimum. The design suits offices, libraries, cafés, and online meetings where surrounding noise can be a concern.


Both new colors are available through Sanwa Direct and selected online retailers including Rakuten, Yahoo! Shopping, au Pay Market, and Amazon.
