Elecom will release "Slint," a slim and lightweight rechargeable four-button wireless mouse, in late May 2026[1]. Measuring about 26mm thick and weighing roughly 64g, it also lets users switch between up to three devices using both 2.4GHz wireless and Bluetooth[1]. The street price is 3,980 yen, and it comes in black and white[1].
A Slim, Lightweight Design at 26mm and About 64g
Slint's defining trait is a design built entirely around portability. The body measures about 60mm wide, 111mm deep, and 26mm tall, with a weight of roughly 64g[1]. That is lighter than a typical smartphone, so it fits easily into a bag pocket without becoming a burden, making it simple to carry to a cafe or on a business trip[1].
The mouse runs on a built-in rechargeable lithium-ion battery and charges through a USB Type-C port on the body[1]. A single full charge lasts up to about 10 months, which removes the hassle of frequent charging or battery swaps[1]. If the charge runs low while you are out, the bundled USB-A to USB Type-C cable lets you top it up quickly from a PC or other device[1]. A symmetrical left-right design also means it suits both right-handed and left-handed users, which pairs well with on-the-go use[1].
Multi-Device Connectivity for Up to Three Devices
Slint ships with a receiver for 2.4GHz wireless connections and also supports Bluetooth[1]. Users can register one device over 2.4GHz wireless and two over Bluetooth, for a total of up to three, and switch between them with a button on the back of the body[1]. That makes it possible to use a PC at home and a tablet on the go with a single mouse[1].
Supported operating systems span Windows 11/10, macOS Tahoe 26, iOS 26, iPadOS 26, Android 16, and ChromeOS, and any device that supports Bluetooth Low Energy can connect without using the receiver[1]. The ability to connect without occupying a port is convenient for thin laptops and tablets that have few USB ports[1]. For tracking, it uses a BlueLED sensor that works reliably on wood, resin, and glass surfaces, with a sensor resolution of 1,600 DPI[1].
A Four-Button Layout with Silent Switches and a "Back" Button
For operation, Slint adopts a four-button layout that adds a "back" button alongside the left and right buttons and the wheel[1]. When browsing the web, you can return to the previous page without clicking the on-screen arrow, reducing the number of steps in browsing[1].
It uses silent switches that minimize clicking noise, making it easier to be considerate of those nearby during meetings or while working in the early morning or at night[1]. Each button can be assigned a preferred function using the free "Elecom Mouse Assistant" software, allowing customization to match how you work[1]. The model numbers are M-TM25MBMSBK for black and M-TM25MBMSWH for white, both at the same price[1][2].
Summary
Elecom's "Slint" is a four-button wireless mouse that packs portability-focused features into a slim, lightweight body measuring about 26mm thick and 64g: multi-device connectivity for up to three devices, silent switches, and a rechargeable battery that lasts about 10 months. For anyone who works across multiple PCs and tablets, it stands out as an option worth considering.
