5 Fuji guides, rings are gray. They are Al2O3 (commonly known as alumina) instead of SiC. These were removed from an old bait rod. There are scratches and dullness on the metal parts, but there are no deformations or ring damage that would interfere with use. LN type gray (alumina) guides are not often seen. Sizes (measured): ・Top: Tip 3mm, Ring inner diameter 6mm ・2nd: Double foot, Ring inner diameter 6mm ・3rd: Double foot, Ring inner diameter 6mm ・4th: Double foot, Ring inner diameter 7mm ・5th: Double foot, Ring inner diameter 8mm LNSG (SiC version of the same shape) is about 600 yen per piece new, so I think it's a good deal.
