Obsessed with these lashes

Oh my goodness, I tried the Glamour Volume Magnetic Lashes and the Magnetic Eyeliner, and I am absolutely in love! They went on so easily, and they stayed put all day. I usually struggle with lashes but these were a game changer. My eyes looked amazing! I will totally be buying more of their products. Definitely recommending these to everyone I know!

Good value for a kit

I was looking for some DIY lash extensions and saw TB Cosmetics. I got the DIY Lash Extensions kit when it was on sale for about 15% off. Shipping was free over $50, which was nice. It definitely felt worth the money I paid. The quality was good for the price and the instructions were clear.

Hey guys, thinking about getting the magnetic eyeliner kit from TB Cosmetics. Is it actually safe for sensitive eyes? I've had issues with other brands.

A Ashley 4 days ago
Yeah, I have super sensitive eyes and their stuff has been fine for me. No irritation or anything after wearing them all day.

They say it's hypoallergenic on their site, and I haven't had any problems. I usually react to everything, but their magnetic liner is chill.

How long do these DIY lash extensions actually last? Like, could I wear them for a few days without them falling off or getting super messy?

C Chris H. 1 month ago
I've gotten 5-7 days out of mine easy. Just gotta be gentle when washing your face. My friend even showers with hers on.

I think they say up to a week, but honestly, it depends on how well you put them on and if you're rubbing your eyes a lot. I usually get about 4 days.
