Pair of 123 Blocks Set with Screw 23 Holes 1/10,000th Precision with Case

These are one of the cheapest set of 1-2-3 blocks at Amazon, but I have know doubt they are as good as any other blocks. They’re as accurate as most of any 1-2-3 blocks, except maybe those expensive blocks that are dead nuts accurate. These come in a sturdy plastic case along with a set of machine bolts for the holes in the blocks, if needed. They are coated with a thick layer of oil you’ll need to clean before use. Great set of blocks for most purposes.

Fast shipping well packaged nice blocks

Has everything needed to make full use of all functions. This set Mic's out really close to spec's. No rust when received.
