- Customizable firmness :
Please note that some models do not support firmness customization. Be sure to check the options and alerts on the product page.
Please note: For safety reasons, it is recommended to choose soft or medium firmness for deep training toys.
When selecting firmness, please consider the following points:
1. Size of the Toy: Although made from the same firmness, smaller toys will generally feel softer compared to larger ones. Toys with a thicker shaft usually feel harder.
2. Stability: Some models, especially those with a very slender shaft or a large amount of space behind the knot, may not stand on their own regardless of firmness(Conola, and Hunter Jack). Also some toys like Goblin, which can be top-heavy. Generally, we recommend using medium to firm silicone for larger toys to provide the perfect balance of flexibility and stability.
3. Shape Variation: Due to differences in toy shapes, the perception of firmness may vary. The data provided is for reference only.
Last but not least, what firmness will work best for you is very much a personal decision. While our Customer Service team can't recommend a specific firmness, feel free to reach out with any general questions about our firmness options!
- Choosing Accessories:
Please keep the following in mind:
1. Size: The Vac-u-lock adapter has a certain diameter, so if the model is too small, we won't be able to add the adapter. In this case, you can choose the suction cup adapter.
2. Suction Cup Performance: Some Nothosaur models, such as Graemen, Ranger, and Mephisto, may not have the best suction cup performance due to their overall design. This is unavoidable, but we are working on finding a better solution for you.
3. Tube Toys: These cannot be add a Vac adapter. The placement of the Vac-u-lock hole would interfere with the tube, potentially damaging its functionality.
4. Ovipositor and Ipony: These models also cannot have a Vac-u-lock adapter added, as it would compromise the original design and functionality of the product.
