Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
Assuming a mold costs x then to produce a normal set 4 different molds are required. If each mold lasts 5,000 uses then 5,000 boxes of product needs 4 molds = 1 mold / 1,250 boxes.
Now the mini series require 1 mold and this mold lasts for 5,000 uses too. However, at 4 uses per box, only 1,250 boxes can be produced before another mold is needed.
So whichever wat you look at it, the costs of 1 mold need to be amortised over 1,250 boxes regardless of whether the box is standard or mini.
