What Makes a Good BIAB Brand?

Not all builder gels are created equal. Before diving into individual brands, here are the key factors that separate a great BIAB product from an average one:

• Formula quality — A good builder gel should be self-levelling, meaning it settles into a smooth, even layer without excessive manipulation. This saves time during application and produces a cleaner result.
• Colour range — More shades means more versatility. Some brands offer dozens of colours while others focus on a smaller curated palette.
• Soak-off capability — Soak-off formulas can be removed with acetone, which is far gentler on natural nails than filing off a hard gel. This is a significant factor for long-term nail health.
• Price per application — The sticker price on a bottle only tells part of the story. Consider how many full sets you get per bottle and whether the formula requires one coat or multiple.
• Australian availability — Some international brands ship directly to AU, others rely on distributors, and a few restrict sales to licensed professionals only. Ease of purchase matters for restocking.

Brand Reviews

OPAL Beauty

OPAL is an Australian brand offering 78 BIAB shades at $29.95 per 15 ml bottle. The range is named after iconic Australian locations — from coastal nudes to bold statement colours — and every shade is vegan and cruelty-free. The formula is a soak-off builder gel, so removal is acetone-based rather than requiring heavy filing.

OPAL's builder gel is used by over 1,000 salons across Australia, and the colour range is one of the broadest available from a single brand. The self-levelling formula works well for both overlays and short extensions.

Worth noting:OPAL's BIAB range is relatively newer compared to some established international brands, and there is no dedicated starter kit available yet. If you're just getting into BIAB, you'll need to purchase individual bottles and your own lamp, base and top coat separately.

The GelBottle Inc (TGB)

The GelBottle is widely credited with popularising BIAB in the nail industry. Based in the UK, TGB has built a strong following among Australian nail technicians thanks to its excellent self-levelling formula and a wide shade range that covers everything from sheer nudes to rich colours.

TGB sits at a premium price point and operates a professional-only distribution model in Australia — you typically need to verify your qualifications to purchase. This exclusivity is part of its appeal for salon professionals but makes it less accessible for home users or students.

Worth noting: Shipping from international distributors can add to the cost and lead time. Stock availability in Australia has improved over the past year, but popular shades can still sell out quickly.

Mitty

Mitty is an Australian-owned brand that has built a solid reputation for accessible, quality nail products. Their builder gel range offers a good selection of shades at a competitive price point, making it a popular choice for both professionals and home users who are new to BIAB.

Being Australian-based means fast domestic shipping and local customer support, which is a genuine advantage when you need to restock quickly or have questions about products.

Worth noting:Mitty's builder gel range is smaller than some competitors, so if you need a very specific shade you may find the selection limiting.

Ugly Duckling

Ugly Duckling is a professional-focused brand known for high-quality formulas across their nail product range. Their builder gel is well-regarded by technicians for its consistency and workability, particularly for sculpting and overlay work.

The brand positions itself firmly in the professional market, with pricing and distribution that reflects that focus. Their educational content and technician support are strong points.

Worth noting: Availability in Australia can vary depending on your location, and the colour range for builder gels specifically is more limited than brands that focus exclusively on BIAB.

Kodi Professional

Kodi Professional is an Eastern European brand that has been gaining traction in Australia. Known for a wide product range and competitive pricing, Kodi offers builder gels that have found favour with technicians looking for reliable formulas at a lower price point.

The brand has a growing Australian distributor network, which has improved availability and shipping times compared to a few years ago.

Worth noting: As a newer entrant to the Australian market, Kodi may be less familiar to clients who specifically ask for well-known brands. The product range and shade availability can also shift depending on distributor stock.
