Neat lot of "ball bearing" MICROS - Each one has a ball bearing in the chassis that Speedeez claimed was for speed. I am pretty sure these are all Speedeez (My eyes can't read the bases well)
These are similar in size to Micro Machines. (About 1 3/8"-1 1/2" long)
All are Good Condition, some do have more playwear than the others. Take a good look at the pics.
