1929 Kashin Cards question

[vintage954]

I recently picked up a lot on ebay and most of the cards were listed as EXMT, but it seems that most are a tad short of the 3 3/8x 4 1/2. Are these known to come from the factory like this or should i be concerned? The edges feel smooth even on all cards even the two that measure out perfect.

Might want to post this in the pre war section as you are more likely to get a response from someone knowledgeable.
