B1. Maximize precision.

The B1 is built on the experience of professional gamers. The result is a new type of mouse bungee that is both steadier and more flexible – all to help gamers perform better.

Unique, flexible construction.

In order to truly enhance player performance, the bungee needs to be flexible enough to follow every mouse movement without resistance. The B1 is uniquely constructed to help gamers improve their play, and features a flexible silicone arm that moves with the player, making the mouse feel wireless.


Stable bungee, solid play.

With a low center of gravity, non-slip rubber feet and a weight of almost half a kilo, the B1 is a super-steady bungee guaranteed to stay in place during the most demanding gaming situations.

Built-in USB hub.

The B1 not only makes your mouse movements smoother, it also helps you organize your gaming area by bringing a 4-port USB hub to the table.

Swedish design.

The B1 is a more stylistically pure mouse bungee, featuring a sleek steel design combined with an Xtrfy yellow LED illumination. The steel of the chassis is hand-brushed, which makes every copy of the B1 unique.

Developed by elite gamers.

As one of the most successful teams in the history of eSports, Ninjas in Pyjamas know what it takes to win. This mouse bungee is developed in collaboration with NiP.


”The B1 has a new construction that makes it more flexible than any other mouse bungee, providing smoother movements and better mouse control.”
