【Simulated Multi-Sound Silencer】This type of silencer with dividers consumes energy sequentially as the high-pressure gas ejected from the muzzle passes through the layers of panels, gradually expanding and forming a vortex to slow the impact velocity. The pressure decreases as the gas is released at the tip of the silencer, reducing noise.

【Vocal Practice】No more worrying about complaints from neighbors when practicing vocal exercises at home. Practice at your own pace at home.

【Emotional Release】When you feel stressed, you can release it anywhere. You can even yell into the bottle. There's no need to worry about affecting others.

【Multiple Uses】Not only can it be used as a silencer bottle, but also as a vase when you have free time. The bottle can also be used for DIY painting.
