Great skin quality ! All the shiros will get better with time, the sumi is not through strong as they were grown on in warm water over the winter. The only reason we can do these auction prices, is they have been grown on since last year when they were shipped as tosai. Please collect or arrange to ship koi within 10 ten days of the auction. Koi can be shipped at £30 per box, this size you can get at least 6 in if your looking to buy multiple koi.Sex cannot be guaranteed at auction prices.
