SWISOK Toys offers three standard levels of firmness for you to choose from when selecting from the menu: “Soft”, “Medium” and “Hard”. Our toy firmness scales are specified in a range of three grade points, from Soft (5), which is approximately matches Shore 0050, to Hard (9).
  • Introduction of the three types of firmness
Here are examples of Fenrir's Size M. We have placed each of our three firmness dildos - Soft(5), Medium(7), and Hard(9) - on the same level with a vertical ground. The best way to explain the difference is to compare the degree of stand-up of our three levels of firmness.

The picture shows the difference in the degree to which the three scales of hardness stand up. In the same size, the "Soft" firmness Fenrir sags, not perpendicular to the ground; the "Medium" firmness Fenrir is approximately perpendicular to the ground, but still slightly sagging; the "Hard" firmness Fenrir is approximately perpendicular to the ground.
  • Explain the difference by squeezing the three hardnesses of the toy
We will explain the difference between the three firmnesses in a second way. By squeezing as hard as possible using the same force, you can see the different degrees of squeezing that each of the different hardnesses is subjected to.


The feel of our soft (5) is softer and easily compressed, like a relaxed muscle. This makes for an easier ride!



Our Medium (7) is slightly inflated, similar to a semi-tensile muscle, adding some precision in comparison to Soft (5), while also being flexible.


Our Hard (9) has almost no squeeze, is stiffer, more pronounced toughness and will have less rebound.


Our customers generally report that our medium firmness feels more realistic and skin-friendly, and it offers a balance of riding precision and flexibility. It depends on whether you prefer the firmer or softer side of your toy.


  • Steps for selecting firmness on the product page
We would make your toy softer or firmer at no extra cost. Simply select the appropriate level of firmness from your toy menu. If you wish to change the softness or firmness after placing your order, please contact us promptly by email. We will manually change the hardness of your toy for you.
As an example, on the following product page, after selecting the size and color of the product, click on the option of firmness, then add to the shopping cart and purchase it!

  • Note 
  1. The firmness option will not be supported in some categories due to the construction and characteristics of some products. For example, Masturbator, Urethral Sounds, and Penis Sleeve. These three ranges of toys will not be able to be selected for the firmness scale.
  2. The larger the size of the product chosen, the less noticeable the hardness of the product. In the case of the same softness, the toy feels softer in the hand the smaller it is.
  3. The firmness mentioned above is simply for reference, please choose the most suitable firmness according to your personal situation.
  4.  Due to the natural variation in density between batches of silicone, we cannot guarantee the exact firmness of any pour. Nevertheless, we always try to get as close as possible to the firmness you want.
  5.  Regardless of the hardness, these toys are durable and flexible and can be bent in any direction. Even when hard, they can be bent so that their tips touch the bottom of the base.

We offer color customization options for almost all models. Except for some products, it is not possible to customize a certain color type due to the construction and characteristics.
