This ingenious little gadget allows you to easily work on studs to finish them, after the findings have been attached. 
As an example: I embed my stud finding in the clay piece itself. In the past it was always a tricky thing to then finish them with resin or any other sealant without considerable difficulty.
 
This raised "shelf", which is 8 x 7.3 cm, has its own legs that keeps it just under 2cm off of the table, while the shelf itself has 36 holes in it, meaning that you can finish multiple pairs all at the same time.
