I personally find the portable chalkboard to be the perfect accompaniment to Jeppscotch.
Whilst one may always have their dice and chalk to hand, there is not always an ideal location or environment in which to play matches.
Besides there is so much more one can create with a chalkboard than say for example, a Chess board, and it is for this reason I will always favour Jeppscotch over any other game.
There are numerous companies manufacturing and selling chalkboards of various sizes and these can be found all over the world wide web.
Most of these companies have a storefront within the Amazon network, so get over there and grab one today!
