Pretty average
These clip in extensions (I wouldn't describe them as a topper in any way) are ok. They are average quality synthetic clip in with a small mesh base. The clips open and close well. The fiber is not responsive to low heat at all (picture comparison above) so you are pretty much limited to stick straight styles with these, which is fine if that's what you are looking for, and you will need to powder or dry shampoo them to reduce the shine and make them look more natural. I got the 4503 which on the website looked like a silver and was described as Beige silver. Well, they are definitely beige not so much silver, actually a solid color (not a blend) champagne think would be a good descriptor. Overall, ok if you are looking for something very specific (side and back clip ins, stick straight, and champagne color) these could work for you, they were just not what I was looking for.
