Would 15x11x7 would be too big for the 600-800 gram bps? Would it be okay if i put a 600-800g bp in the 15x11x7 if i stuff it with some newspaper so the bp doesnt rattel around? Because different size boxes make it difficult to buy in bulk so id rather just get a box that will fit all of the sizes of my snakes. (Smallest one i want to ship is about 650g)
