The GelBottle - 20 Fibre BIAB Builder Gel, 20ml

The GelBottle Fibre BIAB – 20, 20ml

The GelBottle Fibre BIAB — 20 is a warm nude tinted with a flush of pink, made for neutral BIAB nails. It's part of the brand's Fibre BIAB Colour Collection, where thousands of microscopic Nylon-66 microfibres are dispersed through the gel, adding structural support that resists breakage and improves durability compared to a standard builder gel. The warm, pink-flushed nude makes shade 20 an easy everyday choice that works beautifully on its own or as a base for other looks.

This is a TPO and HEMA-free formula, made in the UK, and works as a base, builder gel, and sculpting gel all in one. It's suitable for natural nail overlays as well as extensions, and it's compatible with The GelBottle's DesignEx Pro system. A newly designed anti-leak C-curve brush makes application cleaner and gives better control around the cuticle area, while the self-levelling formula helps create a smooth apex without extra effort.

How to Use

For extension work, pair it with Rubber Base or Bond Base to support optimal adhesion and retention. Follow The GelBottle's full application guide for cure times and structuring steps.
