removing commas from a list and just keeping the elements

I have the following list, I want to remove all commas and just be left with the elements of the set.

Tuples[{I, l}, 16]  {{I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I}, {I, I, I, I, I, I,        I, I, I, I, I, I, I, I, I, l}, {I, I, I, I, I, I, I, I, I, I, I, I,        I, I, l, I}, {I, I, I, I, I, I, I, I, I, I, I, I, I, I, l, l}, ....} 

EDIT: So what I want is something like:

{{IIIIIIIIIIIIIIII}, {IIIIIIIIIIIIIIIl}, {IIIIIIIIIIIIIIlI}, {IIIIIIIIIIIIIIll}, ....}
