- Choose your size:
Nothosaur's toys are made from high-quality platinum silicone, which is soft and stretch, so they aren't as hard as some 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 a smaller size. Nothosaur offers three or more sizes for each toy so that our customers 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. Nothosaur also designs toys with themes like tentacles and aliens, catering to niche fetish interests, just like ours. Explore to your heart's content at Nothosaur!

- Customizable firmness :
They come in three varieties of firmness: Soft, Medium, and Hard. Choosing one of these options means that the entire toy will be custom in a single hardness. We ship firmness: Medium by default.
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. And for more firmness info, please check this: Firmness Guide
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:
Most Nothosaur toys come with suction cups that can adhere to smooth surfaces, and we love using them this way too. Nothosaur's suction cups are included at no extra cost. However, if you want your toy to be compatible with sex machines, you can opt to add a Vac-u-lock attachment.
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.

What is vac u lock?
The Vac-U-Lock is a crucial component for connecting sex toys to sex machines, ensuring a secure and compatible fit. It’s important to note that different sex machines require specific Vac-U-Lock accessories. In other words, the adapter is a vital part of the attachment system for sex toys.
At Nothosaur, our Quick Air Connector may require an adapter for use with certain devices, ensuring seamless integration with your specific equipment.
How does vac u lock work?
Each toy is designed with a hole at its base for the Vac U Lock attachments. These attachments are meant to fit into this specific hole. Once the plug is inserted, it creates a vacuum seal, ensuring the attachment is securely in place during use.
When the adapter is inserted, it locks in firmly. To remove it, simply slide your fingers alongside the adapter to break the seal and take it out.
The size of the holes might make it a bit tricky to insert the attachments, but a little water-based lube can help you get a snug fit without too much effort.
