From XactRC is this 28 compartment small parts case box which contains 7 smaller containers. Each of the 7 smaller containers has 4 individual compartments. Each compartment comes with a label to go over the lid to help you better organise your parts. Each compartment has the approximate dimensions of Length 24mm, Width 20.5mm, Height 21mm. The transparent XactRC triangle sticker allows you to still see into the box to find your items. Great way to keep your suspension pills, screws, and washers organised. Also available in a 56 compartment version, it is similar to the 28 but includes 14 smaller containers with the same size.
