Extreme Shell-F Slide Case

The Max Cases Extreme Shell-F Slide Case fits Lenovo 300e and 500e G3 Chromebook or Windows 11" devices. A thermoplastic polyurethane shell wraps the laptop in a gray and clear finish. The slide design lets the device enter and exit quickly. Rugged materials resist scratches, dirt, oil, impacts and drops.

Replaces basic sleeves and loose bags

A simple fabric sleeve cannot stop a corner impact or an oily fingerprint. This case upgrades protection when the laptop moves between classrooms, bags or desks. The jump is worth it when daily handling risks bumps, spills or grit that would mark an unprotected chassis.

Fits an 11.9" by 9.7" footprint at 1.4" thick

The shell adds 0.9 lbs and stays within the device profile so it slides into existing backpack compartments. Ports, buttons and vents remain accessible through precise cut-outs. The non-slip TPU surface grips the desk and frees the user from a separate sleeve.

Questions about this item

Will the 9.7" depth and 11.9" width match my Lenovo 300e G3 11" Chromebook?

Yes, the Extreme Shell-F Slide Case is built for Lenovo 300e and 500e G3 11" models, so the 9.7" D x 11.9" W footprint aligns with those devices.

How does the slide-on TPU shell go on, and what step do people miss?

Slide the top edge in first, then press the bottom until it clicks; the common miss is leaving the bottom corners unseated, which lets the case shift on drops.

When should I replace the TPU shell if it stays scratch- and oil-resistant?

Replace it once the material shows cracks, permanent deformation or the corner lips no longer grip the chassis, as impact protection drops sharply after that.
