PREFACE:
How small it is? There is a real story about it.
Once these tiny disc were half finished,our workers put them on the working table to check the dimesion.but when she came back in the afternoon,these magnets are gone. They could not find it anyway.The truth is,another worker took them as dust on the table and rubbed them away.
Please look carefully,it is the easy to be ignored part I'm trying to promote.
As you can see in the picture,the worm-like part is the D0.9*0.5 Ndfeb magnets.
