I am offering for sale a Vintage Sugino Double-ended Cone Wrench Set 13mm/14mm & 15mm/16mm. 

Indispensable "must have tools" for maintenance of older non-sealed bearing type hubs, and many high-end hubs which continue to use cone and bearing systems.

Very nice condition.  A few dimples in 15/16mm ends-will not affect function.  See pictures.
