Any beginning watchmaker is going to buy this Chinese oiler set with four oilers and a 3 part oil cup. Here is the ideal way to organize it! You just shove the oiler cap into the hole, the oiler now sits in the cap loosely. The oil cup just sits in the space. The two little holes up front are to put some Rodico in, to wipe off your oilers.
