Oh my what can I KNOT say in this review! 😁I have been very pleased within your heart shape cupping its everything and more!! I love that the material is hard plastic feel then typical cupping sets are that are easily to crack. I haven't dropped thes bad girls yet I'm preventing that! Ha. I just simply love the sturdiness, the glide I can do with it. I love them my clients are loving it especially because its heart shape during valentines month. The price is worth the investment.
