Tanos has inserts and systainers for the Multimaster. I got mine from Woodcraft. I one for my Multimaster and a syst I for my accessories. Both are grey and I got orange latches for them also.
I have one of these with an orange latch, but I would love to have the orange one because it's orange and says Fein on it.
