## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect!
*by C***R on August 11, 2019*

perfect metal spheres. If you need metal spheres for a project these are great. You can weld on them and the bond is great. I use them in metal art projects and have yet find any flaw with them. Cutting them is not bad but they are strong and seem to be hardened. My metal band saw didn't have any trouble cutting them but I did break a couple of drill bits in the press putting holes in them (may have been not enough lube on the bit during drilling). I love the structural strength of them.

### ⭐⭐⭐⭐⭐ Good,metal
*by P***K on December 17, 2023*

Welds good. Heavy enough to drill and tapand holds bolts

### ⭐⭐⭐⭐⭐ Odd item for a restoration
*by D***7 on April 1, 2025*

Perfect item for an antique restoration of two old floor lamps I am doing. Once attached they will be the balance weights.Well made, good price, Amazon service as good as ever.
