Dermaplane Facial Exfoliator Replacement Heads

Not compatible with SIMA Spa science Dermaplanning tool! Buyer beware. Amazon is linking these two to buy together, although they are not compatible. I have a sima spy, science, derma planner, when I bought it Amazon suggested I buy these with it. Thinking they were refills I got them. Save yourself the money and time don’t make the same mistake. I’m reading Amazon three here for pairing them together. I’ve not been able to use them so I’m not actually reading the product.
