Big, solid, strong. It includes a big white bag, a laser-cut 8mm thick
'ice' acrylic board and 48 25mm phenolic resin balls (same material as
snooker balls) in 3 colours (16 each of white, black and red), and a
sheet with rules for 7 games.
The phenolic balls are the same as the Shogun set. You can see a size comparison between Samurai and Ninja in a picture below.
Although they are not needed, optionaly you can purchase bowls for the marbles in the 'Extras' section. Each bowl can handle 16 phenolic balls (so you'll need 3 bowls).
The rule book is not included. You can order the full-colour, professionally bound book describing the system and the best 30 Shibumi games so far, including the Shibumi Challenge prize winners and several other of our favourite entries, HERE. All of the profits derived from the sales of this book will be donated to ayudarjugando.org.
UPDATE: You can now purchase the book directly here, on nestorgames!
