I never really thought s100 and p21s smelled nearly as strongly of crayons as 16 did, but hey, thats just me. Now, where the heck is my 64 pack of crayons.......
Oh, definitely not as strong as #16 (which is like sniffing a tin of concentrated robin's egg blue crayons). But, to me anyway, P21S/S100 has that same underlying scent that reminds me of grade school.
