Manufacturer description
The Hermitshell Hard Travel Case is built for one job: getting a Logitech MX Master mouse from desk to bag to desk without picking up bumps, dents, or scratches along the way. The molded EVA shell fits the MX Master 4, MX Master 3, and MX Master 3S, and this 2.0 upgrade revision tightens the interior so your mouse does not shake or slide around in transit. If you commute with your mouse, move between a home office and a client site, or throw your kit in a backpack alongside a laptop and a charger, this is the layer that keeps the scroll wheel and side buttons from taking abuse.

SpecPicks Verdict
SpecPicks scored Hermitshell Hard Travel Case using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Hermitshell's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Does this case fit the MX Master 3S?
Yes. Hermitshell lists this 2.0 upgrade version as made to fit the Logitech MX Master 4, MX Master 3, and MX Master 3S Advanced Wireless Mouse.
Does the mouse come with the case?
No. This listing is for the case only. The device and accessories are sold separately, so you need to already own an MX Master mouse.
What is the case made of?
EVA, a semi-rigid foam material. It is a hard shell designed to protect your mouse from bumps, dents, and scratches rather than a soft fabric sleeve.
Will my mouse rattle around inside?
This is the 2.0 upgrade version, which Hermitshell markets as No Shake, meaning the interior is shaped to hold the MX Master in place during transport.
Is this case worth it for the price?
It is a small fraction of an MX Master's cost. Check the listing for current price, which varies.
