Thank you for viewing. First come, first served. This is a set of 4 plates, each 5kg, for a total of 20kg. Please assess the condition from the images. As these are used items, please refrain from purchasing if you are concerned. I am not currently considering price reductions. They can be used with 28mm shafts, so they are compatible with Irotec and Fighting Road shafts. The navy blue ones have slightly larger holes. Thank you.
