I have the Beginner anal kit and it's pretty good but not really designed for long-term wear and it doesn't take much for some of them to slip out, but if you are willing to explore different textures while still being on the small side, it's a good kit to get.
The beginner anal kit because its silicone. The Juli Ashton sucks, it was my first kit before coming to EF and learning about materials and it just sucks. It has a smell that even after almsot a year and tons of cleaning won't go away no matter what I do.
I have the beginner anal kit, and I really like it. It's 100% silicone, so it's very safe. The textures and shapes are all really interesting and a great intro to texture.
The only problem I have with them is that they aren't designed for long term wear or use, since the bases are so widely flared that they press against the cheeks and might get uncomfortable.
