Hair Volume Boost Invisible Sponge Bases Fluffy Bump Up Puff Insert Foam 2 Pieces One big One small

My hair has gotten so thin on the top. I thought these would help me get more volume. It says they are invisible. But they aren't. Maybe if I had gotten dark brown instead of black, they might have not shown as much. Because my hair is thin, there's not much to cover these up. It comes with two different sizes. You really have to work with them to get them not to show.

The small one is great for a hair clip poof and the large one creates a more 50's look. I like them a lot, I just wish they weren't black, as I have blonde hair.
