Japanese Pebbles:  Simply Natural Japanese pebbles are the ideal natural substrate to use for creating truly stunning displays of colour in the home or garden. Most of our pebbles come from the exotic islands of Asia, and average 40mm (1.5ins) in size. Not only can these pebbles be used to create beautiful landscapes, but they can also enhance flower displays and candle holders etc. All our pebbles are entirely natural and, as such, they will retain their vibrant colouring without fading. Pebbles are supplied in 20kg bags, each bag giving suitable coverage for an area 0.4 metres approx (an area of 1m x 5m, for example, will require 12 bags). Up to three bags can be posted direct, but quantities over 60kg will be sent on a pallet.
