WARNING: THIS SET IS SMALL
This really is a travel set. Gemma used one once on the Eurostar. It was great for that. You could use it on a coffee table or something as well if you're currently enjoying the London housing crisis and eating, sleeping and ******* in one small room. However, in all normal situations and with normal sized human hands, this isn't great.
That said, this set being priced at the lower point is good for those players who are just wanting to test the waters. Or as before, you have space restrictions or don't want to carry a heavy tileset.
