Yes you need to prove your qualifications.
Please don't let the packaging put you off. The products inside are great. I switched to them from a white bottle this year and my clients have loved it. Their gels are very pigmented, most are one coat. They offer great user support and are really upping their game with new colour releases. They offer gel colours, 15 colours of builder in a bottle, 3 base coats, 4 topcoats, gel paints, glitter, all sorts of nail art stuff.
Depending on what brand you're used to, it can be a learning curve. You can't be sloppy with your prep. But there's loads of demo's in the CJP user group showing how to use each product correctly
