Foam Lined

Pick 'n Pluck
The case comes filled with foam that is pre-scored in 1/2" by 1/2" squares that are easily removable to create your own custom interior. The lid generally has a solid or convoluted (egg crate) foam filling. This type of foam is primarily designed for smaller case applications and size limitations do apply.

Custom Foam

This is the preferred foam interior for delicate electronic pieces such as computers, monitors, video gear, and all other types of fragile equipment.
