Mutanttoys makes two anal plugs that frequently appear on recommendation lists: the BERG and the YURA. Both are body-safe liquid silicone butt plugs designed for extended wear, but they’re quite different in practice. If you’re trying to decide between them, this comparison will help.
Overview
The BERG and YURA are Mutanttoys’ core anal plug offerings. Both share the same premium liquid silicone construction and body-safe design philosophy—but they differ significantly in size, contour, and use case.
Size Comparison
This is where they differ most significantly:
- BERG: Larger, wider contour. Best suited for intermediate to experienced anal plug users or those specifically interested in extended wear with a more substantial presence.
- YURA: Smaller, thinner profile. Designed for beginners or those who prefer a lighter, more subtle plug. Easier to insert and comfortable for longer wear.
Contour & Shape
BERG: Features an ergonomic contour designed to sit securely against the body. The shape is more pronounced—wider at the widest point and with a defined neck-to-base transition. Designed for stability during extended wear.
YURA: Has a gentler contour with a thinner profile throughout. The shape tapers more gradually, making insertion easier and more comfortable for extended periods. Better for beginners or those sensitive to pronounced shapes.
Best Use Cases
| Scenario | Recommended |
|---|---|
| Complete beginner to anal play | YURA |
| Intermediate user wanting larger plug | BERG |
| Extended wear (hours) | BERG (more secure), YURA (lighter weight) |
| Frequent daily wear | YURA (lower fatigue) |
| First anal toy purchase | YURA |
| Wanting a substantial presence | BERG |
Material & Quality
Both are 100% liquid silicone, so there’s no quality difference. Both are non-porous, hypoallergenic, boilable for sterilization, and compatible with water-based lubricants. The silicone density and finish are equivalent— Mutanttoys doesn’t compromise on material quality across its product line.
Extended Wear Comparison
Extended wear—the practice of wearing an anal plug for hours during normal activities—is one of the more popular uses for plugs like these. For extended wear:
BERG: The more substantial presence creates a more noticeable “full” sensation during extended wear. The ergonomic base sits securely. However, the larger size means more muscle engagement to keep it in, which can cause fatigue over very long periods (4+ hours).
YURA: Lighter and less fatiguing for all-day wear. The thinner profile is less demanding on the sphincter muscles. Better for daily extended wear. Less pronounced sensation—some users who want a stronger “full” feeling may find it too subtle for extended wear purposes.
Which Should You Choose?
Choose BERG if:
- You have some experience with anal play already
- You want a more substantial presence
- Extended wear is important but you want a secure, ergonomic fit
- You’re interested in a larger size as a goal toy
Choose YURA if:
- You’re entirely new to anal play
- You want a comfortable everyday plug
- You prefer a lighter, less fatiguing experience
- You want to start small and potentially size up later
The Bottom Line
The BERG and YURA aren’t competing against each other—they serve different users and different use cases. The YURA is the right starting point for almost everyone. The BERG is the logical next step when you’ve outgrown the YURA or know you want a more substantial toy from the start.
The good news: both are excellent. Mutanttoys has made two genuinely well-designed anal plugs with the same premium liquid silicone quality. You can’t really make a wrong choice—you’re just choosing where to start.
