I LOVE this mixing bowl set!!  Sturdy plastic, rubber bottom (removable rubber pieces) and rubber thumb tab on side (not removable) is so great in securing the bowl while I stir/whisk!  They are vibrant, shiny, beautiful bowls and do great in dishwasher (though I opt to remove the rubber bottom pieces for this).  They are a beloved replacement for my Cuisinart 3pc stainless steel mixing bowls that I lost in a home fire.  If I drop a bowl, It's not deafeningly loud when it hits the floor and what's MORE - It's MUCH quieter to use a hand mixer with!  DEFINITELY RECOMMEND x 100%.  I got mine on sale for twenty dollars, but they are worth the regular full price of thirty dollars!!
