WEN 10423 3 x 2 x 1-Inch Steel-Hardened Precision 123 Blocks, Two Pack

The blocks are so helpful , good purchase!

Nice 123 blocks

These things work fantastic. Great for woodworking.

These 123 blocks are cheaply made and not suitable for more precise work.

Excellent seller! Good product!

Well made for the cost

I bought this product to use for making sure items are square and for accurate measurements and it seems to work.

Be forewarned, these blocks reek of Chinese machine oil. I had to spray them with brake cleaner, then wash them with soap and water to get rid of the oil. Otherwise, they do the job.

theyre literally just metal blocks what could you possibly mess up here

I ordered 2 blocks.
