Surface Roughness Standards Set – 30 Specimens

Great condition, easy to use as per its purpose.Arrived quickly. Supplier is very reasonable and trustworthy.

Useful to know the international standard

Just a roughness reference to make sure the roughness meter works well, nice pouch, portable, well built.

Standard were pretty good quality but attention to detail was pretty bad, the stickers that label the different standards were so crooked that they actually covered a portion of the standards themselves. Would expect better for price point.

Nice
