How to choose the hardness of your sex toy

The hardnesses we offer in our silicone toys

One of the most important criteria in the choice of silicone sex toys is hardness. It will affect the usability of the final product, as well as the feel to the touch provided by the toy. So, choosing the right hardness is key.


We work with the following harnesses : 

  • Harder (20A) - only for small-sized dildos

  • Hard (12A) - only for medium-sized dildos

  • Medium (7A)

  • Soft (3A)

  • Extra soft (00-20) - only for masturbators

By default, we make each toy with a specific hardness. It can be personalized but, there are some restrictions beyond which we cannot go. Basically, the bigger the toy, the softer is the maximum hardness that we can use. For instance, the Harder one (20A) can only be used in small toys. On the other hand, the Extra soft is reserved exclusively for masturbators.

The meaning of each hardness

Before having it in the hand, the best way to understand how much hard something is by comparing with known objects. The hardness of our silicone is around the hardness of our bodies, that's why they feel so realistic. So, let’s compare the hardness of our silicone with the hardness of our bodies.

In the following graph, we have a scale (from 0 to 90 A) showing how much hard are different body parts (on the softest region, on the left) and several other objects (on the right). Have a look:

Comparison of known objects with Shore A hardness scale


Fatty body parts, such as gluteus and belly, are very soft: they deform easily and can be squished. Muscles, when they are relaxed, are also easily squished but, they offer more resistance than fat. Pushing the bones which are cover by a layer fat, like the hip or ribs, give the feeling of slightly more resistance than relaxed muscles. And tensed muscles are slightly harder than these bones. Finally, exposed bones, such the clavicle are the most harder parts of our bodies. Of course, the hardness feeling depends on your own fat quantity and muscle development.

The hardness of our silicones

Now, with respect to our silicone, extra soft and softer feel like a fatty belly, the difference we made between them is that we use the former for dildos and the latter for masturbators. Soft and medium feel like a relaxed muscle, with some resistance to bend but not much. Hard feels a bit soft but it's harder to bend. The harder, like a tensed muscle, feels quite firm and, being difficult to bend, doesn’t bend much. 



Mind that, the thicker is the toy, the harder is the feeling: the bigger toys will always feel harder. That is partially the reason because we don't make all sizes in all possible hardness, the big ones become just too much rigid (both to be used and to take them out of the moulds!).
