I like those Phi-Kari models but having had to go on a hunt to find out who these people are I found where the first kickstarter models are on sale;

On the plus side they appear to be pewter, on the negative the quality of casts they are showing for promotion is not the best. Also I cant find out how big these are beyond 'microscale', what on earth does that mean?
Edited to add: It does state that models are 1-2.5 inches long but does not specify actually how big specific, individual models are.
