Capturing the dark allure of the deep sea, the Abyssal Siren Throwdown is a Signature NUC design. A base of teal spray paint fractured with black crackle sets the tone, while blue–purple chameleon chunky glitter shimmers like scales beneath the surface. Overlaid with holographic scale foils and flecks of fine black glitter, every angle reveals new flashes of light and shadow. Finished with a flowing dark teal ink swirl, accented with Caribbean blue and white highlights, this tumbler evokes the pull of ocean currents and the haunting mystery of sirens’ song.
⚡ Please note: This listing is for the Signature Upgrade only and must be purchased with a Classic Custom Base in your chosen size (20oz, 30oz, or 40oz). Without a base, this upgrade cannot be fulfilled.

Where beauty turns to mystery, the Abyssal Siren Throwdown waits. This darker counterpart to the Moonlit Mermaid tumbler captures the untamed, shadowed magic of the ocean depths.
The base begins with rich teal spray paint, fractured by a bold layer of black crackle effect that reveals a sense of hidden power. Beneath this lies a mesmerising foundation of chunky blue–purple chameleon glitter, shifting and shimmering like scales beneath the surface. Delicate holographic scale foils shimmer across the tumbler, catching flashes of light like a siren’s lure.
To deepen the design, fine black glitter fills the gaps, adding contrast and a sense of depth. Finally, a moody dark teal ink swirl, kissed with pops of Caribbean blue and white, flows across the piece, evoking ocean currents that pull you further into the abyss.
Every detail of the Abyssal Siren Throwdown speaks of mystery, allure, and danger — a tumbler for those who feel most at home in the shadows of the sea.
🔹 Available Sizes
20oz Signature Standard – sleek, versatile, and bold.
30oz Curve Premium Upgrade – the curved shape enhances the shifting light and scale foils, making this design even more hypnotic.
Handcrafted as part of the NUC Signature Throwdown Series, each piece is one-of-a-kind, just like the sirens of legend.
✨ Why Upgrade to the 30oz Curve?
The 30oz Curve isn’t just larger — its unique shape transforms the way light dances across the design. The gentle curve enhances the shimmer of the glitter, deepens the layers of colour, and creates a striking play of highlights that you simply don’t see on a straight tumbler. If you love bold, dramatic sparkle, the 30oz Curve Premium Upgrade is the ultimate way to showcase your Signature Throwdown in all its glory.
Care Instructions for Your Tumbler:
Thank you for choosing Naughty Unicorn Creations to create your tumbler. To ensure the longevity and vibrancy of your custom creation, please follow these care instructions:
1. Handwash Only:
Handwashing is the key to preserving the quality and lifespan of your tumbler. Gently clean the exterior and interior with a mild detergent, warm water, and a soft sponge or cloth. Avoid abrasive cleaners or scouring pads, as they may scratch the surface.
2. Avoid Dishwasher:
Resist the temptation to toss your tumbler into the dishwasher. The high temperatures and harsh detergents used in dishwashers can compromise the integrity of the design and finish. Handwashing ensures a gentle touch that keeps your tumbler looking fabulous.
3. No Microwave, Please:
Our 20oz Stanley-style tumblers are not microwave-safe. Exposing the tumbler to extreme heat can affect both the design and the structural integrity. If you enjoy hot beverages, we recommend transferring them to a microwave-safe container before heating.
4. Handle with Care:
While our tumblers are built for adventure, they still appreciate a little TLC. Avoid dropping or subjecting your tumbler to rough handling to prevent any potential damage to the design or structure.
5. Caution with Abrasives:
Be mindful of surfaces and substances that may cause abrasion. While our tumblers are durable, unnecessary rough handling against abrasive surfaces can affect the finish over time. Treat your tumbler with care to maintain its original charm.
6. Check for Wear and Tear:
Regularly inspect your tumbler for any signs of wear and tear. If you notice any issues, contact us promptly for guidance on how to address them. We're here to ensure your tumbler stays as beautiful as the day you received it.
By following these care instructions, you'll keep your Naughty Unicorn Creations tumbler looking fantastic, sip after sip. If you have any questions or concerns about caring for your tumbler, feel free to reach out to our customer support team.
