What is halfgeng?

Halfgeng is a unique flow and manipulation prop developed by RD Buugeng. As the name suggests, it’s “half a buugeng” – when you combine two and hold them by the smaller inner rings, they form the classic full buugeng shape.

Its design takes inspiration from both buugeng and Russian-style fans. This hybrid nature makes Halfgeng incredibly versatile, allowing for fan spinning, contact work, juggling, balancing, and even hoop-style manipulation.

Still a relatively new prop in the flow arts world, Halfgeng invites performers and artists to explore fresh movement possibilities and push the boundaries of creative expression.

Super durable and really bright! I like that when the pink ones are under UV light that they’re more of a hot pink/fiery red. Awesome that they come with a case and the strings even match the prop!

FAQ

What is Halfgeng?

Halfgeng is a unique fusion of Buugeng and Russian Fan. This gives the prop a unique shape and allows for a different range of movements and visual effects.

Should I get Buugeng or Halfgeng?

If you are at the beginning of your flow journey or have a fan spinning background, then we believe you would enjoy our halfgengs more. They have an easier learning curve and plenty of similar tricks with fans. It is also easier for many people to dance with them.

If you want to dive into the world of object manipulation to the fullest, we recommend getting buugeng. It’s a prop with a longer history than halfgengs and offers a broader range of tricks and different approaches to using them.

If you already tried spinning 4 buugengs aka quad buugeng, we recommend getting 4 halfgengs to explore more object manipulation possibilities.

Halfgeng vs Buugeng: What's the difference?

Halfgeng and Buugeng are based on the same geometry, but as Halfgeng’s name suggests it is only half of Buugeng and you control it by spinning it around your hand using the circle. Meanwhile to master Buugeng you need to learn finger spinning or wrist spinning. This difference in construction as well as the way of controlling them gives the two props different movement possibilities and visual effects.

Where can I learn more about using Halfgeng?

We created an online course with 19 lessons that are available for free here: Halfgeng: getting started course

UV Color on Halfgeng? How Does it Work?

UV color is a special feature on our Halfgeng products that creates a unique visual effect under black light which is a type of ultraviolet light. This effect is created by using special paints that react to UV light, causing the Halfgeng to appear to glow. UV color is a great way to add an extra level of visual interest to your Halfgeng performances or jams, and is sure to capture the attention of your audience. To experience the UV effect, simply flow with your Halfgeng in dark under black light, which is usually available at most parties and festivals.

Can you do custom orders?

Yes! Contact us in advance to go over your requirements and let’s create your dream set together.

Is Halfgeng made to order or ready to ship?

Plastic Halfgeng is ready to ship, usually within 1–3 working days. Wooden Halfgeng is made to order due to the wide range of color options. Please allow 5–10 working days for us to craft it just for you.

How long does it take to receive my Halfgeng?

We ship via express delivery, using trusted couriers like UPS, DHL, and DPD. Within the EU, we’ve also added several local courier options so you can choose the delivery service that works best for you.

Delivery times vary by location, but we always aim to ship your Halfgeng as quickly as possible. You’ll receive tracking info once it’s on the way!

Is Halfgeng sold as a single piece or a pair?

Every Halfgeng set comes as a pair – always two pieces.

What’s the best material: wood or plastic Halfgeng?

Both materials have their strengths – it depends on your style.

Wooden Halfgeng is vibrant, customizable, and perfect for expressive, visually striking flow. Plastic Halfgeng is ultra-durable, smoother to the touch, and built for endless practice – making it a great choice for beginners, too. If you value bold aesthetics and traditional feel, go with wood. If you’re after resilience and a sleek, minimal look, plastic might be your match.

Can I use Halfgeng for fire spinning?

Only our Fire Halfgeng is designed for fire spinning. Our standard wooden and plastic Halfgeng models are not fire-safe and should never be used with flames. If you’re looking to spin fire, check out our specially designed Fire Halfgeng, crafted with heat-resistant materials and optimized for safe fire performances.
