It’s not easy to keep makeup from smudging in the summer due to the heat and sweat! I’ve found that even if my skin makeup wears off, if I apply eye makeup in a way that prevents it from smudging, my overall makeup seems to last a bit longer!! That’s why I place so much importance on my eyes, and this eyeliner was one I bought in a hurry at Daiso!! The pen is thin, the color comes out thick, and it seems to last well. I really loved it, and I think you all know the price without me even mentioning it!! So, I’ve settled on this Daiso eyeliner!! Since eyes are important in the summer and eyeliner is a must, I recommend it! The price isn't a burden, so it’s worth giving it a try. If you need one urgently, give it a go!
