PartyWoo Black Balloons Arch Kit, 152-Piece Set (18/12/10/5 Inch Black Balloons)

If you’re building a balloon arch or garland and you don’t want to play “guess the right sizes,” this PartyWoo Black Balloons set is designed for that job. It comes with a mix of 18 inch, 12 inch, 10 inch, and 5 inch black balloons meant to stack together for a fuller look. The set also leans into practicality: the balloons are described as thick and durable latex, and the small sizes are there to fill space so your centerpiece or backdrop doesn’t look empty.

That said, it’s not perfect for every balloon plan. The 5 inch balloons are specifically noted as not floating when inflated with helium, so if your goal is a floating helium look, you may need a different approach.

The essentials

This is a 152-piece black balloon assortment meant for party décor setups like balloon arches, garlands, and centerpieces. The mix includes: - 18 inch balloons (4 pcs) - 12 inch balloons (30 pcs) - 10 inch balloons (35 pcs) - 5 inch balloons (83 pcs)

On paper, the size distribution is what makes it useful: the bigger balloons give you structure and “wow” in the arch shape, while the 5 inch balloons help you fill gaps around the frame for a more even, dense look.

What matters most in use

The product is framed around staying power and setup speed. The balloons are made with thick, durable latex so they’re expected to stay fuller longer (the goal is “setup to celebration end,” not just a quick photo moment). For filling, the guidance is straightforward: fill with air for best results, and they can stay full for up to 72 hours.

There’s also a helpful detail for inflation: the balloons have standard necks, described as allowing quick inflation. If you’ve ever wrestled with balloons that take forever to pump or don’t expand evenly, you’ll appreciate that this set is meant to be easy to blow up.

And yes, there’s a limitation to keep in mind: the 5 inch balloons are stated as not floating when inflated with helium. So, if your plan is helium + buoyant mini balloons, this kit may not match what you’re imagining.

Key features that affect your results

These balloons are positioned for repeated party use cases rather than a one-off decoration. They’re marketed for events like birthdays, graduation, baby showers, anniversaries, weddings, and other celebration-style themes.

What you’ll really notice day to day is the “how it looks after you build it” factor. Thicker latex and a mixed-size layout are exactly the ingredients for an arch or garland that holds its shape through the day.

Still, you’ll need to manage inflation carefully. The instructions specifically warn not to overfill and to avoid sunburn/overheating, pointed objects, and excessive friction. In plain terms: if you over-inflate, you risk compromising the look or durability.

Who it’s for (and who should skip it)

It makes sense if you’re planning a black-themed décor setup—balloon arches, garlands, or a centerpiece—where you want multiple sizes in one bag. It also fits event types where you’re likely decorating over a few hours and want the balloon display to stay looking decent into the celebration.

It may not suit you if your centerpiece relies on helium-floating balloons, especially if you were counting on the 5 inch balloons to float. Also, if you’re trying to create an extremely minimal look with only a couple sizes, this assortment might be more than what you need.

Practical tips before you commit

Before buying, consider how you want your décor to be filled and displayed. If you’re filling with air, the provided guidance suggests the balloons can stay full up to 72 hours, which aligns well with most party timelines. If you’re inflating everything to the same size without adjusting, you may end up with a less natural arch shape—part of the instructions is controlling the amount of air to reach your ideal balloon size.

Also think about logistics: more pieces (152 total) means more inflation work, even if the necks are described as quick to inflate. If you’re short on time, plan for extra hands or a faster inflation method.

What’s included

The package includes black balloons in multiple sizes: 18 inch (4 pcs), 12 inch (30 pcs), 10 inch (35 pcs), and 5 inch (83 pcs), for a total of 152 balloons.

Final verdict

Worth considering if you want an all-in-one black balloon arch/garland kit with a mix of large and small sizes, and you’re planning to use air for a décor display that stays full for up to 72 hours. It’s a solid pick for most party setups that need density and shape.

Skip it if your main goal is helium-floating mini balloons—especially the 5 inch sizes—because the instructions say they could not float when inflated with helium. It also may not be the best match if you want a very simple décor scheme using only one or two balloon sizes.
