Each TT set acts as a part in an organised system by being clicked together with other TT sets and fits perfectly in your service case, tool box or roller cabinet. No space is wasted and each tool sits perfectly in place. This means it is much easier to see whether any tools are missing at the end of the day.5 Steps to Get OrganizedChoose storage: case/top box, middle box or roller cabinetChoose the TT- sets you would like.Take off the lidClick the sets togetherPlace them in the storage!
