Thank you for viewing. This is a weight set from IGNIO. [Set Contents] - Brand: IGNIO - Weight plates: 2.5kg x 2 - Weight plates: 1.5kg x 2 - Shaft: 1.7kg x 1 - Nuts: 0.2kg x 2 Including the shaft and nuts, you can use it in 3 ways: - Approximately 5kg (1.5kg x 2) - Approximately 7kg (2.5kg x 2) - Approximately 10kg (1.5kg and 2.5kg x 2) The plates are all coated. I have been using them indoors. The corners are cut to be safe, so they are safe even if children touch them. As you can see in the photos, there is some wear and tear, so please purchase if you don't mind.
