TORMEN 150pcs Eyeshadow Shields are well made and designed for creating a "no mistake" zone under the eye for my mascara application. These are great in that they apply quickly and are convenient to protect from mishaps with the mascara wand that is bound to happen with my waterproof mascara that otherwise would be a bear to get off the undereye skin! These have just the right amount of adhesive to stay put, but are gentle on the undereye skin when slowly removed. They are a good assist for undereye liner, too. I use cream eyeshadow sticks usually, but on occasion that I use a powder, these are helpful in catching the powder that falls from the applicator wand making for easy cleanup! I can see where these could be helpful for eyebrow makeup application, but haven't had a need for them, so far. I am please with the quantity you receive, the quality and effectiveness of these shields!
