This 3.5" Hard Disk Drive protective sleeve is made from soft flexible silicon rubber.  

It absorbs vibrations and bumps to protect the hard disk inside.

The SATA connector is exposed when the top is removed so that it can be inserted into a USB dock while leaving the protective body in place.

Air vents on both sides allow for cooling while the disk is in use.

The design has a "window" to the top of the hard drive, enabling any label on the hard drive to be seen for identication purposes.

The sleeve is designed so that multiple disks can be stacked.

They are supplied in a set of 4 individual sleeves.

If you purchase 2 packs (so 8 sleeves in total) you will get free UK delivery.
