Survived the rain!
I labeled some garden pots with these markers and left them outside through a heavy storm. The writing didn't budge or fade at all. Highly recommend for any outdoor labeling needs.

Perfect for street art projects
These markers are incredibly vibrant. The oil-based ink sticks to everything I've tried, including glass bottles and metal signs. The dual tips give me great versatility for both filling large areas and adding fine details.

Professional grade results
I use these for prototyping on various materials. The fade resistance is real; I have samples from six months ago that look as fresh as day one. The fine tip is precise enough for intricate work.

Great colors, strong smell initially
The color selection is fantastic and they are truly waterproof once dried. There is a slight chemical smell when you first open them, so I recommend using them in a well-ventilated area. Otherwise, excellent quality.

Good value for money
For the price, you get a solid set of markers. The black and white are particularly opaque. I took off one star because the cap on the blue marker was slightly loose, but the ink itself is top-notch.

Students love them
Bought these for my high school art class. The students appreciate the smooth flow of the ink and the durability of the tips. They haven't dried out even after weeks of intermittent use.
Q: Are these markers safe to use on food containers?
A: While the ink is non-toxic once fully cured, we do not recommend using these markers on surfaces that will come into direct contact with food or drink. They are best suited for decorative or labeling purposes on the exterior of containers.
Q: What is the shelf life of these markers if unopened?
A: If kept sealed in their original packaging and stored in a cool, dry place away from direct sunlight, these markers have a shelf life of approximately 3 years from the date of manufacture.
Q: Can I refill these markers when they run out?
A: No, the Sinier Dual-Tip Markers are designed as disposable units and cannot be refilled. Once the ink is depleted, the entire marker should be recycled according to your local regulations.
Q: Do these work well on dark surfaces?
A: Yes, the oil-based formula is highly opaque, making the lighter colors visible on dark surfaces. For the best results on black or very dark materials, we suggest applying two coats and letting the first layer dry completely.
Q: How long does it take for the ink to become waterproof?
A: The ink typically dries to the touch within 2-5 minutes depending on the surface porosity. However, for full water resistance and durability, we recommend allowing 24 hours for the ink to completely cure before exposing it to moisture.
