NSI have a soak off builder gel system. It’s called NSI Secrets. The clear gel is great for art as it’s perfectly crystal clear.
Be aware though, it takes a while to soak off, even after debulking with an efile.
Also watch out for heat spikes and remember to flash cure before fully curing... before the lamp nanny’s jump on me this phenomenon is normal for the product and is mentioned in the instructions! NSI do not have any particular insistence on which lamp to use
but if you have one with the facility to
primarily ‘soft’ cure first that would be handy.
Apart from these two issues the gel is lovely to work with and self levels nicely.
