Solid Brass, But Disc Edge Very Rough

Solid brass as advertised, but disc edge is very rough from punch tool and will require filing and polishing to look as good as shown in photos.

The copper was clean and straight

The copper was clean and straight, but the brass wire was all kinky and not in a straight spiral definitely would’ve been nicer to Not have the Brass bent up

Hi Joshua, thank you for your feedback. We're glad you liked the copper wire. Due to packaging constraints, some wires may arrive bent. We appreciate your understanding. Thanks for shopping with us!

Wheelchair caster nut cap was missing

Hospice had given us a wheelchair that the caster nut cap was missing. So I replaced it with the 28mm tube cap. It was of good quality, sturdy and fit perfect. shipping was fast too.

Although it is marked 32-35

Although it is marked 32-35, it is only 15mm, which is of zero use for me.

Perfect they are really made well and I used them for my car

Perfect they are really made well and I used them for my car. The only thing I had a great for us. It took three weeks to get here. So shipping was slow.
