Selecting a size:
Our toys are made from high-quality platinum silicone, which is softer and stretchier than other materials on the market. However, this doesn't mean you should hastily choose a large size. If you're a beginner, we recommend starting with smaller sizes and working your way up to larger ones. By default, we offer three or more sizes for each toy so that you can find the perfect fit.
Fantasy toys come with unique shapes and textures, so it's crucial to choose a dildo that meets your specific needs or desires. We design our toys thematically, such as tentacles and aliens, catering to diverse kinks and fetishes. Explore to your heart's content at Nothosaur!

Choosing a color scheme:
Our toys can be customized in many ways to meet the needs of our customers but, due to the different characteristics of each toy, the style of customization could vary. Please check the custom color options on each product page.
🎨 Here is the Customization Process, please read it before ordering. (Customization Process)

- Selecting a firmness:
We offer three varieties of firmness; Soft, Medium, and Hard. Our toys will be produced in the firmness type that you select. By default, our toys are produced in our Medium firmness option. Some of our toys do not support firmness customization so please be sure to check the options and alerts on the product page.
For safety reasons,we recommend choosing soft or medium firmness for deep training toys.
When selecting firmness, please consider the following points:
1. Size: Regardless of firmness selection, smaller toys will generally feel softer when compared to larger ones in the same firmness option. Additionally, toys with a thicker shaft usually feel harder than thinner toys.
2. Stability: Some of our toys, especially those which are top-heavy or have slender shafts, may not stand completely upright, regardless of firmness (e.g. Conola and Goblin). Generally, we recommend using the medium or hard options for larger toys to provide the perfect balance of flexibility and stability.
3. Shape: Due to differences in toy shapes, the perception of firmness may vary. The data provided is for reference only.
Finally, the firmness option which is best for you is very much personal preference. While our Customer Service team cannot recommend a specific firmness for you, please feel free to reach out with any general questions about our firmness options!
Choosing accessories:
Most of our toys come with suction cups that can securely connect to smooth, flat surfaces, providing great stability for riding. In those cases, the suction cup is included at no extra cost. However, if you want your toy to be compatible with sex machines, you may wish to change this option to a Vac-U-Lock adapter instead.
Please keep the following in mind:
1. Size: The Vac-U-Lock adapter has a standardised diameter, so we won't be able to add the adapter to our smallest models.
2. Performance: Some of our models have a weaker suction cup than others due to the shape and design of the toy (e.g Graemen or Mephisto).
3. Cumtubes: We are unable to add the Vac-U-Lock adapter to cumtube toys as the placement of the Vac-U-Lock hole would interfere with the tube, potentially damaging its functionality.
4. Ovipositors and Plugs: We are unable to add the Vac-U-Lock adapter to ovipositors and plugs as it would compromise the functionality of the product.
Vac-U-Lock vs. Suction Cup:
When choosing the Vac-U-Lock adapter option, please be aware that this removes the suction cup functionality from the toy. If you decide that you want both functionalities, you can purchase a toy with a Vac-U-Lock hole, and then purchase a suction cup adapter for the best of both worlds.
