Anthony, this is all the information on the item number: Fabri-Kal Alur RD32 32 oz. Clear PET Plastic Round Deli Container 50 / Pack (999RD32)
Suzi, I just used a drill with 1/8" bit through 4 cups at the time and put about 10 holes in the bottom and top cup
Thanks Jon, these are pretty sturdy cups so they should last a while.
