Give your compact reader a clean black finish while keeping its lightweight form easy to carry. This reversible 3D-printed shell is designed for XTEINK X4 and supports daily reading at home, at work, during commutes, and while traveling.

How does the reversible design work? Snap the shell over the front during storage to help shield the display from scratches, scuffs, minor bumps, and contact with other items in a bag. When you are ready to read, remove it, flip the orientation, and attach it to the rear.

The rear-mounted position gives the protector a practical place to stay during reading and creates a firmer handheld surface. A granular back-panel texture improves grip, helps reduce slipping, and makes fingerprints less noticeable. The 7.5 mm profile keeps the setup compact, while the built-in attachment hole and included wrist lanyard add convenience for walking, waiting, commuting, or relaxing away from home.

What is included? The package contains one black protective shell and one wrist lanyard. The reading device is not included. What size is it? The shell measures 4.88 x 2.80 x 0.30 inches and weighs 0.03 lb. Is it made for other readers? No. Confirm that your device is compatible with XTEINK X4 before ordering.

The black finish offers a neutral, understated appearance suited to workspaces, travel gear, and everyday carry. Because each shell is made through a 3D-printing process, fine layer lines or slight surface variations may be visible and are normal results of production. Install and remove it gently, and keep the interior free of debris to help maintain a clean fit.
