Finding ways of storing integrated circuits with either the Dual Inline Package (DIP) or the TO-220 style has been a challenge. If placed in an insert, DIPs often have their pins bent or some how tangle themselves together. These are derivatives based on the packaging that ICs often come in and sized to fit neatly into a Raaco tray.
The DIP sleeve fits ten 8-pin or five 16-pin chips.
Or the TO-220 sleeve fits ten.
Mix-and-match of inserts along with IC sleeves. The DIP sleeves stack three deep.
