Overall, the quality of these brushes is quite excellent. The bristles are soft, the design is nice. Beside that, I have some complaints about these brushes as well. When I first cleanse it, a lot of bristles from the duo fibre, larger shader, and the powder brush fellout. According to the brush guide, it suggests me to spot cleanse it before the first use, but I deep cleansed it instead just because I prefer deep clean rather than spot clean. I'm pretty sure I did everything correctly. I have read the brush guide, and watched several videos on how to wash your makeup brushes from Michelle Phan, Blair Fowler, Kandee Johnson, etc. I even bought the brush guards to properly protect and store these brushes. However, the duo fibre, larger shader, and the powder brush keep shedding bristles crazily. Also, after the first clean, the foundation brush seems to loss its softness. The bristles feel completely different than the first time I feel it when I first got the kit. Whenever I use it to apply my foundation, it tends topoke my skin, and my skin gets a little bit irritated from that. Also after the first clean, the tapered blending brush kinda lost its original shape/form. The tip of the bristles used to be fluffy and spread out at the end, but now the bristles are kinda closed inward, which makes the brush lost its original shape/form. Despite those three problems above, I'm absolutely in love with the rest.
