The Costail moves when you move. Using unique motion technology sensors detect your body movements and motors ensures the tail follows your every move. Simply control it with your hips, by shifting your weight from side to side! It also moves when you are standing still. Check out our How it works page to find even more information!

YES! The Costail has a pause mode that is activated if you stand still for more than 2 seconds. That way you can chill out while there is a small tail party going on in the back. You can check out videos of the pause mode on the How it works page.

The Costail moves according to your movements which means that if you move a lot; the tail moves a lot, and if you slow down the; tail will calm down with you. You are in total control, and with practice you can become quite the tail whisperer. As a second option you can loosen the chord that makes the tail move. This will reduce the movement as well. You can of course change this back back later.

If you want the tail to move more, you can active Boost Mode. You do this by leaning forward or backwards for 5 seconds after turning on the tail. After the tail has calibrated for 5 seconds, you can try to move your hips in a normal position, and the movement should be bigger and the tail more sensitive.

The tail has a mechanical design that ensures its shape stays the same even when it’s turned off. There will even still be some discrete movement when you walk. If you are worried about the tail running out of battery we suggest bringing an extra powerbank so you easily can switch power source if needed.

The best way to understand how to put on the tail is to take a look at the video on the how it works page.

The Costail is fastened to your hips with two belts. The belts carry a harness that sits comfortably on your lower back. The tail slides into the harness with ease. Put on the tail in 3 easy steps:

1. 1. Attach the harness to the belts. You don't have to use the included belts, if you prefer you can use your own.
2. 2. Fasten the belts around your hips, with the harness placed in the middle of your lower back.
3. 3. Slide the tail into the harness! It can now be taken on and off without removing the belt or the harness.

Yes, the Costail comes with two adjustable one-size-fits-all belts. The reason there are two belts is because cosplayers who tested our early prototypes pointed out that to smaller belts were easier to hide under their cosplay than a single large belt. It also helps stabilize the tail, and makes sure you have a comfortable tail session! However, you are welcome to use your own belts if you wish to do so, as the harness is compatible with belts of almost all sizes. Check out our How it works page to find even more information!

We recommend watching the Costail assembly video for putting the tail together.
