Shipping & Customer Service

blendStick's top priority is the satisfaction of our customers.

We offer free shipping to all locations.

However, tariffs are significantly impacting the speed and cost of our shipments. Therefore, our current fulfillment time could be increased by a few days for certain products. Our average delivery time is currently 7-15 days. As we are a small business, we hope you understand the circumstances. We believe that keeping our products high quality is worth having slightly longer shipping times, and we hope that you agree.

Nonetheless, we promise to try our best to reduce the delays. We will communicate with you during the entire process and ensure there is no confusion about your product's shipment.

You will also receive a tracking number with each order so you can track your package at any time.

We are working on reducing our shipping times in the near future. Thank you for your support!

Brows That Look Like Yours — Only Better


The precision 4-D prong tip lays down fine, hair-like strokes — no guessing, no harsh lines.

Testimonials

  • Actually Looks Real..


    This is the first brow pen I’ve used that actually mimics real brow hairs. The angled prongs are perfect for shaping and flicking upward strokes. I even get compliments asking if I had microblading done. Super precise, but still quick to use.

  • So Unique!


    I’ve tried so many brow pens, but nothing gives me that hair-like definition like this one. The 4-prong tip makes it so easy to fill in sparse spots without it looking blocky or drawn on. My brows finally look natural but sculpted.

  • Beginner Friendly!


    What I love most is that I don’t need to be a makeup pro to get amazing results. The brush design almost guides your hand and it naturally creates those soft strokes instead of harsh lines. It lasts all day without smudging too, which is a huge win for me.

Frequently Asked Questions

Can I use it on empty or overplucked brows?


Absolutely. The 4D multi-prong tip is perfect for mimicking real hairs, making it ideal for filling in gaps or shaping thin brows naturally.


Does the pen dry out quickly?


Not if used and stored properly. Always cap the pen tightly after use, and store it tip-down to keep the ink flowing.



Is this waterproof or smudge-proof?


Yes — Blendstick is formulated to be both smudge-resistant and water-resistant, lasting all day through sweat, humidity, and light rain.
