## Customer Reviews

### ⭐⭐⭐⭐⭐ What you see is what you get
*by R***T on February 27, 2023*

I can confirm that this is indeed a smallish sized block of graphite, and not a candy bar.

### ⭐⭐⭐⭐ OTOOLWORLD 99.9% Purity Graphite Block
*by A***. on June 20, 2025*

Exactly what I needed to make impossible to get brushes for an old shop bench grinder. I was able to carefully carve out pieces from the block with a band saw and file to make new brushes.

### ⭐⭐⭐ Not strong enough for carving small models
*by C***C on July 30, 2024*

This brand of graphite isn't suited for small detail carving. It isn't as strong as other brands I've used. I've tossed models 20 feet across concrete without breaking them, but a ring model I made from this cracked with simple handling. Small features I carved came away in little chunks rather than sharp chips and fine powder. I'm giving it 3 stars rather than 1 star because the job I'm using this for is very specific, and I think it will handle more common tasks just fine.
