Sonia G The Lotus Set is a limited edition brush that retails for $215.00.
Sonia G The Lotus Set Summer 2021 Brush Set ($215.00) is a new, limited edition set that features a different-colored ferrule and handle compared to the brand's permanent brushes. The set includes six brushes; three for face and three for eyes. Three of the brushes are very similar to existing, core brushes (one is exactly the same).
I'd consider this a semi-review as there are three brushes that are similar to past releases, so I have more knowledge on those, but there are three that are new to the set, so those may be more like initial impressions. Sonia G.'s quality has been high that I feel comfortable releasing initial impressions, as I have not had issues with brushes degrading over time and usually find I love a brush more over time rather than go the other direction. I have replaced most of my go-tos over the years with Sonia G. brushes.
