Pull out the tool box a bit. I want the thickness of the material to be as thick as the tool box. Three small accessories on the lid are very handy and useful. Also it is convenient because you can wear the partitions freely.
I think that the price is the highest, but I am sure of making it. There is a volume with a lid at the upper part, but this is very handy. There is neither a poor feeling that the lid will immediately become useless. I like it very much.
