Frequently Asked Questions
Is this authentic?
Yes. Every item is bought from an official seller in Japan, or direct from the brand for pre-orders,
never from resellers or grey market stock. Counterfeits and grey market listings are a real problem in
Asian beauty online, and buying only through official channels is how we rule it out.
What are your shipping rates?
On orders under US$75, shipping is a flat US$20 to the United States and US$10 to all other countries.
Orders of US$75 or more ship free, applied automatically at checkout. Your exact shipping cost is shown before you pay.

I like perm/I love clumping/I hate fibers/I hate volume. This sheer color mascara can be applied with a comb-shaped brush and easily creates clumps. It also doesn't come off easily. I love this series and have bought many colors, but my favorite is brown. It's a stylish color that gives a slightly casual feel. When I want to make my eyes look more powerful, I use black or navy. It's a bit disappointing that it becomes harder to clump as the liquid gets low, but for this quality and price, I'll probably continue to buy it again.
I keep buying the transparent black. It doesn't feel like you're wearing mascara, and it naturally accentuates your natural eyelashes, so it's perfect for everyday use. The liquid isn't thick or sticky, so even if you accidentally get it on your eyelids, it's easy to recover, which is helpful for me as I'm not very good with my hands. What I like most about it is how well the curl lasts, and how my eyelashes don't turn white even after a while of application. Until now, when I used mascara that had a good curl, there was a high chance that my eyelashes would turn white by the evening, but with this mascara, my eyelashes stay black from the time I put it on in the morning until I took my makeup off, so it's great.
I bought BK-1. I was looking for a mascara like this because I don't like it getting on my lower eyelids over time. It's a light clear black, so it's easy to apply, and the curl retention isn't too bad. I think it might make my lashes a little longer. I'm glad I bought it because it doesn't get on my lower eyelids even after a while.
I've bought this product many times! It doesn't stick too tightly, so it gives you natural looking eyelashes.
It's light, so it doesn't clump and is easy to apply. I use it for eyelashes, so I just use this.
