Very good product

Good product

Been ordering for years now, these last couple of shipments have been terrible. Seems like they changed manufacturing, not charcoal anymore. I have 4 boxes that I can’t use because it’s so messy, gets stuck on my fingers now like pre-ink. One line on my client and i have to get a new string, terrible!

I bought this product as a recommendation from a brow artist so I bought it and it worked great the first time!! When I went to purchase again, this time around it was horrible! I kept pulling the string out over and over because I thought the first time it wasn’t saturated in the ink enough. Nope! I only got one good line before it stoped working. So I returned the product. I was so happy to find this product when I first used it. So I’m not sure what’s going on with this last batch I got?

Works exactly as desired. Easy to clean and definitely leaves a mark where you want it.

Great quality

I got this for doing my own brows at home to make sure i'm making them as even as possible. the thread works well but it's very messy. I would recommend wearing gloves. Now that I have used it I can see that a lighter colour like white would be better. I have dark brows and the black lines resemble dark hair too closely and contrasting colour would be better.

This was my GO TO mapping string, however i just ordered another 2 and it seems they changed the product, same design just the string and ink is different. I’ll be quite honest it sucks now, it isn’t precise anymore and the link only lasts for me to make 2 lines. I really hope this brand will go back to using their previous supplier. Otherwise I won’t be re purchasing anymore

I have been ordering this for a few years now and I don’t know if they changed the product or this is a bad batch but the ink on the string is absolutely awful. Dries out within seconds. I have to use a total of 4-5 strings on one client in order to get a full eyebrow mapping. Which never happened before when using this, even my clients can tell
