Deli cup question?

[mmsi1002]

The deli cups i got have absolutely no holes in them. Should there be at least one small hole?

 

[Nigel4less]

Are these for incubation, humid hides or what?

 

[Bodon]

If taking them to a show or expo to sell id say yes, they need some holes.

for the incubator, no holes is best. I tape over the holes in my delis that house eggs.
