The Jumbo Base has been designed to work with creams and liquids, it’s a mix of sokoho goat combined with several type of synthetic fibers: the natural bristles bring airiness, they add grip, and help absorb or balance the excess oils, while the synthetic fibers facilitate the glide of the brush. It has medium density and feels very soft on the skin. It’s a large brush with a slanted shape, that slanted shape is created by hand by an artisan, only by the same artisan. I had the opportunity to see the manufacturing in person and the shaping technique takes a lot of time, I didn’t see anything like it before. I could not film it because the technique is confidential and they wish to keep it that way, which is understandable but you would not expect this brush to require so much work and I was very surprised to see that this process was so artistic. We use dyed synthetic bristles so that the brush won't look as dirty when used and reused, and we use undyed natural bristles because the components on cream and liquid products may alter the dye that is used on natural britles. The cons of mixing different types of bristles are mainly related to the price because it adds more complexity to the manufacturing process of the brush, therefore more costs. After considering all those pros and cons, we still think it's worth doing this, but the use of a mix of bristles with my brushes is not a means to save costs in any way. This brush can be used for foundation, cream bronzer, or cream blush, to diffuse various cream products or apply hybrid formulas. It doesn't alter the application underneath as it has movement and airiness. I also use it when I want to add more coverage with a powder foundation or set the foundation application with powder. I find foundation brushes are the most tricky to design. It's difficult to design a foundation brush that works with all products and for all skin types, even the weather has an impact on how our products interact with our brushes and our skin. Interesting but challenging! I hope this big brush can be a good fun brush for you too 🤗❤️🖌️ I wish you a fantastic weekend!! #soniagbrushes #beautylish #japanesecraftsmanship
