Bottlebrush - 39 - Professional Biab builder gel - 15ml
Lively, approachable, and named for one of Australia's most recognisable native shrubs, Bottlebrush is a warm, vibrant lime-green with natural cheerfulness. The iconic red bottlebrush flowers inspire this verdant, fresh-toned green that feels both energetic and grounded. As a builder gel, it delivers colour saturation while strengthening nails with every application, perfect for those who refuse to compromise between durability and visual impact.
Bottlebrush is the shade for professionals who smile while they work. Wear it for client-facing roles, outdoor events, creative industries, or any moment when your energy needs to be visible and infectious. The BIAB formula ensures nails stay strong and colour stays true through busy days, while the creamy finish provides application ease that saves time and frustration. This is professional colour with personality.
Skin Tones: Radiant on warm undertones and medium-to-deep complexions; fresh on fair skin with golden warmth; universally flattering in natural light.
Best Worn For: Client meetings, outdoor events, retail environments, creative industry roles, weekend adventures, community events
Pairs With: Grevillea (No. 38), Waratah Rose (No. 33)
How To Use
Start with clean, dry nails. Remove any existing gel, polish, or product completely using an appropriate remover.
Removes natural oils, dust, and any moisture — all of which cause lifting. Then apply nail bond or primer if needed.
Apply a thin, even layer of OPAL Gel Base Coat over the entire nail. Cure immediately under your LED lamp.
Using the OPAL Builder Gel brush, scoop a small bead, place it in the centre of the nail and allow it to self-level for 2–3 seconds before spreading. Cure under LED for 60 seconds.
Apply a second, slightly larger bead for your desired strength and length extension. Cure for 60 seconds.
Using a 100/180-grit Opal nail file, shape the free edge to your desired finish — square, oval, almond, coffin, or round. Work in one direction to prevent cracking.
If applying gel polish colour, apply a thin, even first coat and cure for 60 seconds. Follow with a second coat for full opacity and cure again.
Apply OPAL Gel Top Coat in a smooth, even layer over the entire nail surface. Cap the free edge to seal the product and prevent tip wear. Cure for 60 seconds.
Pro Tip
Allow each bead to self-level for 2–3 seconds before spreading. Work in thin, controlled layers — it’s easier to add thickness than to remove it. Always cap the free edge with your top coat to prevent tip wear.
