I work with Cintia for the past 4 years, she designed my lash manuals (digital and print versions), also helped my team designing the app and I honestly can't see myself working with anyone else and I'll tell you why - her taste. I am always having hard time with digital designers as I don't like anything they propose. Cintia just has implacable sense of taste, she does clean, balanced, elevated work.

She always has very valuable suggestions too which is so incredible important for me personally as I do need help bringing my thoughts to life, I never had to brake down every single word/detail - she does it with you.

Out of question best l've worked with so far, always looking forward to the next thing we create together With so much love, Lena 🫶🏼

I have been purchasing manuals and digital resources from Sinlash since 2021, then again in 2024, and now again in 2026 — and every time I come back, I’m reminded why I keep choosing them.

As a lash trainer, my strength is lashing, competing, and teaching students how to become award-winning lash artists. Designing manuals, presentations, and all the visual materials needed for a course is simply not my strength. Creating something this beautiful and professional is honestly beyond my skill set.

That’s where Sinlash is incredible.

The level of design, structure, and professionalism in these templates is amazing. They make it possible for educators like me to focus on what we do best — teaching and building great lash artists — while still delivering high-quality training materials to our students.

I highly recommend these digital products to any lash trainer who wants to invest in something truly professional for their future students. If you're thinking about it, do the right thing for your course and just go for it.

Trust me — this is 10,000x better than anything you’ll find on Etsy. 😉

I also strongly recommend getting the bundles. They save you so much time and give you everything you need to create a beautiful, organised course.

You will not regret it.

I had my first training and I’m beyond happy with how it went! I decided to go with your lash manual cause it’s so detailed and super easy to use in Canva. It was really important for me to find something I wouldn’t have to edit too much myself, but still have the option to customize since I needed to adjust the content to my wispy techniques.

And the manual is honestly sooo aesthetically beautiful and it matched my studio vibe perfectly!

I’m a lash technician with 9 years of experience, and I’ve been delaying offering courses because I wanted my students to receive only the best possible training material.

Creating a manual myself turned out to be much more difficult and time-consuming than I expected. Luckily, I found Sinlash.

I purchased both the Classic (single lash) and Volume manuals, as well as the website template, and I’m honestly extremely happy with the products. The manuals are editable in Canva, which makes it easy to customize them and adapt them to my own course and brand before offering them to my students.

What really impressed me is how detailed and extensive the manuals are when it comes to lash extension knowledge. They cover everything a student needs to know. From the fundamentals to more advanced concepts and even go beyond that. The information is well-structured, thorough, and clearly written, making it easy for students to understand the theory behind lash extensions.

You can really tell that a lot of experience and knowledge has gone into creating these materials. For anyone looking for high-quality educational resources within the lash industry, these manuals are truly a game changer 👏🏽👏🏽 THANK YOU SO MUCH!!
