I ordered the AliExpress dupe to the Real Techniques Miracle Complexion Sponge back in January last year, and it only cost me $0.70. 😀 But in order for me to truly compare how it looks and feels against the real thing… I had to get the real thing:
The price for the Real Techniques sponge ranges from $7.69 online from the RT store to $11.99 from Rexall (drugstore). I bought mine for $9.99 off NailPolishCanada.com
