Most clear cases are made from TPU (thermoplastic polyurethane). At least one listing describes a case made from plastic.
They help protect the device from scratches, everyday wear and tear, and some drops. The cases are lightweight and designed to guard the Kindle during regular daily use.
The transparent material lets the device’s design show through while providing a protective layer. Many cases also include precise cutouts so buttons and ports remain fully accessible without sacrificing coverage.
They cover common Kindle/e-reader screen sizes, notably 6", 6.8", and 7" models.
Most listings include a single case (package quantity 1). Some options also include three decorative/backer inserts, and certain accessory bundles add charms and a hand grip.
Weights shown in listings range from about 0.07 to 0.15 pounds (examples include 0.07, 0.10, 0.13, and 0.15 lb).
