Review on Ultra Precision Plastic Blocks 0.0001 by Harley Franchetti

I used to have the more expensive 1 2 3 blocks and used them but left them in the garage and they were too rusty to salvage. I bought these as a cheaper replacement and they are the same quality as my previous ones (which cost me twice as much) and came in a case with screws and an Allen key to assemble them into a larger block if needed. Each block was greased and carefully wrapped in industrial grade VCI paper to keep it from rusting during shipping and storage, which was a nice touch. I keep mine indoors so I cleaned and wiped them down with isopropyl alcohol and then applied a light coat of oil to them instead. Just be prepared to clean them before first use. Will definitely be buying another set or 2 for sure in the future.
