Dream it up, then shape it up!

The Flow is a toy all its own. You can bend it, twist it, curve it anyway you want to. In addition the included bullet can be placed anywhere it fits to add your dildo work of art into a vibrator too!
Can customize it, anti-bacterial silicone, nice bullet, multiple uses
May feel a little thin, some things work better than others

extremely useful review


The Flow by SinFive is one of thee most unique toys that I have personally seen in a long time. The Flow has endless possibilities as a dildo/vibrator combo. The key to its design is the twisted dual rods that are covered in silicone and have a metal core allowing them to be twisted and bent every which way. In addition to this, a strong bullet is included. The bullet can be slid into the coils anywhere it pleases. This means that the Flow can be a dildo that becomes a vibrator, a dual penetrator, an anal probe, you name it! Dream it up, then shape it up!

Material / Texture

The Flow is made of 100% anti-microbial silicone. Anti-microbial means that the material has a layer that is added during production. It keeps the material safe from bacteria and micro-organisms. When they come in contact with the material, their metabolism is destroyed, effectively preventing their survival. This process is 99.9% effective and completely safe. It is a softer silicone than many I have used. It has a velvety feel to it with moderate drag, but it still collects a lot of lint and hair. The hair can get annoying something because it will wrap into the toy, especially if your hair is as long as mine is. The royal purple color is really nice for a change. It is almost as deep as eggplant. The Flow also comes in black.

Design / Shape / Size

There is nothing else out there like the Flow. Sure, there are bending toys, but do they twist at the same time too? The Flow can go pretty much any which way you want to bent and twist it. The Flow is basically a metal circle covered in a tube of silicone. Crimp it in half, twist it, and you have a dildo swirled rope! When it is swirled up, it is about 10 1/2" long. The diameter of the toy will change depending on how you shape it or how tight you twist it etc., but on average it is about 1 1/4".

Because of the metal core, it can be bent into a multitude of different ways. The one button bullet that comes with the Flow is pretty standard except that it is slightly linger than standard bullets. It can be slid between any twist of the Flow. It can be bent slightly up at the end to create a g-spot probe. The other end could then be curved up to add the bullet to as a clitoral vibrator too. You could also just leave the bullet closer to the middle so it vibrates better internally. It can be snaked back and forth to make a wavy probe. It can be curved into a 'U' or 'C' so that it can be used for double penetration. If you put the bullet at the end and perhaps give it a bit of a curve, it can be safe for anal penetration too. Depending on how you twist it, it can feel softer or harder inside the body. Basically, dream it up, and bend it up to your heart's content!

The design makes it very discreet in my opinion. While it doesn't look like a regular dildo, it still is curious looking. You might not want to keep it out. It is pretty good for travel. Just make sure to not go through a metal detector with it!

The Flow is a lot of fun to use since you can do so many things with it. While it is not the King or Queen of any trade, it is a jack of many which is very valuable. Vaginally, it feels very interesting-in a good way. Twirled, the twists of the Flow feel very unique to many toys I own. Anally, I am not a huge fan of this, but that may be due to the fact that I prefer more cylindrical shapes. It does work though. It also works for double penetration. If I was not thrusting this toy, I enjoyed it anally a bit more than if I was. The bullet works more effectively depending on where you place it. While the Flow is very bendy, it's not like it is a tub of playdough. It has structural limits. Sometimes what you create will work well and sometimes it won't. Regardless, it is fun to come up with a new tool design and shape to use on yourself or your partner.

By itself, the bullet is strong enough to finish me. I love using it with other toys! In the Flow, it has more of a moderate vibration level. It obviously feels strongest around where it is placed. If it is placed in the middle of the Flow, the ends will have a low vibration. You could always add multiple bullets! Don't be afraid to get creative. I'm sure you could even put another slim dildo or vibe in it cross-ways to create another double penetration device. I had a lot of fun with the Flow!

Care and Maintenance

The awesome thing about this particular material is that it sterilizes itself within 6-8 hours. You still need to clean it though. I suggest completely untwisting the Flow. If you don't gunk can get caught in the major crevasses that are probably created by the design you made. Let it dry and then place it in storage. Use only non-silicone lubricants with this toy. Anything else can ruin the material.
    • Easy to clean
    • Easy to store


The packaging is very simple and also very discreet. The Flow comes in a dark matte, cardboard box that opens from the side. On the outside it has little graphics of what is inside, but the language is very non sexual. The only sexual language appears in very small font on the back. The bullet comes with batteries.
    • Good for storage
    • Minimal
    • Recyclable
Follow-up commentary
I still think the SinFive Flow is a really cool product, but it just doesn't have a place in my go-to toy box. As is, it has a hard time finishing me. It is very arousing though. Even though I say those things, I still recommend it to anyone who likes to be creative. It is a lot of fun to figure out if it can be used with other toys you have!

    Me too I saw that today.

    Yes, you are reading that correctly. This toy only comes with one bullet, but you could totally add more of your own.
