Holds 15-Piece Metric Flex-Head Ratcheting Combination Wrench set #48-22-9513.
The 22 and 21mm wrenches are on the edges and the 20mm wrench is in the middle. Aside from this, all wrenches are arranged in size order. This has been done to accommodate the larger wrenches within the lid recesses.
We now offer labels to identify which tools are in which cases. Labels are available in either black or gray. Please see pictures for color reference, but the labels for this insert will say METRIC FLEX WRENCHES on them.
