The biggest die is 5.5 x 5.5"" & the smallest 0.50" x 0.50" (small 0.25" Increments between dies). The blade is located in the middle of each die. They will ship attached to one another as pictured but I can separate them for you if you wish (this set is easy to detach on your own, grab a nail fine to smooth out the tiny connections) Please look at my other listings and if you would like multiple items, message me. I consolidate shipping costs.
