The plastic protective sheath for 3.5 inch hard drives are designed very solid with hinged lid and snap closure. The hard drives are tight with small cushions held in the housing, so that they are securely positioned in the closed condition and tight. A little more air in the middle of the side walls would be desirable, however, characterized the hard drive could push easily. An optional label on the top of the lid would also be advantageous if there was not the logo.
