Inglot brushes are much cheaper than MAC brushes, and unlike most Sigma brushes that sells merely on the basis of being MAC dupes, Inglot brushes have originality.
I've only got 2 brushes from Inglot so far- 30T angled eyeliner brush & 24SS Dual-sided brush.
Here are my thoughts on them:
Inglot 30T brush
Fiber ~Synthetic Taklon
Price: Rs.640
