yeah i've tried the eyebrow embroidery@ Beafully International actually her shop is at Toa Payoh called Bio-Beauty. Anyway, i went for the 2D/3D Natural Embroidery Creative by Irene Teo. She was really nice and she knew what she was doing the price is also quite affordable at $180-$380.
I strongly recommend you try the eyebrow embroidery by her
you can visit her website @ Bio Beauty
Here are some examples of her satisfied customers: Sara Shantelle, Nicole Chen, Qiu Qiu
