The reversible elastic band makes using both sides mess-free and gives you maximum control while the squishy silicone insert gives the puff a luxe bounce for ultimate application. It also comes with a NEW travel case and mirror for easy puff storage ! For cleansing, it is recommended to use warm water and a drop of the Real Techniques Brush + Sponge Cleansing Gel. Replace every 30 days if you use the sponge side frequently. 100% cruelty-free and vegan. Pro Tip: Pressing your setting powders into the skin helps prevent your foundations or concealers from moving creating the illusion of a smooth, cloud-like base. Try pressing setting powder: under your eyes, on your forehead or chin, or alongside your nose.
