The new gadget toy appears to be selling like hotcakes in China - much to the horror of concerned parents across the country.
The tiny crossbows fire toothpicks powerful enough to break cardboard, apples or even soda cans.
Some cities worried the toys can cause serious injury have now banned them.
According to Chinese media, cities like Chengdu, Kunming and Harbin have already banned sales of the toy, while parents in Hong Kong are also raising concerns.
The small crossbows come as a cheap plastic version for about four yuan (£0.5; $0.6) while the metal versions of the mini weapon cost around 10 yuan.
They are sold in shops and on the streets near schools and are also available online.
Still available online
Reacting to criticism from parents, the country's leading online platforms JD.com and Taobao.com have said they won't allow the toys to be sold any more.
While they are indeed no longer available on those two online shops, they can still be found on other websites like 1688.com, which like Taobao belongs to online retail giant Alibaba.
According to Chinese media, police are also cracking down on shops near schools selling the dangerous gadgets.
Videos on social media showing the crossbows in action have them breaking into cardboard, apples or raw meat.
If the toothpick is replaced with a metal needle, it can even crack through a can of soda.
While the toys do come with a note saying they should not be aimed at people or animals, the packaging of one product claims it can even fight cockroaches, which many might say is no bad thing.
