For many people, summer is not only hot but also full of mosquitoes.

Especially when you lie in bed at night, they will start buzzing in your ears. If you are not careful, they will leave "red envelopes" on your body, making you more and more itchy the more you scratch.

Therefore, many people light mosquito coils to drive away mosquitoes in order to have a good night's sleep.

So, the question is, do you know why mosquito coils have to be put together in two pieces? Let's reveal the answer below!

It turns out that there are several reasons why mosquito coils are put together:

First of all, it is convenient for transportation. Because mosquito coils were invented in Japan a long time ago, two of them are put together, which is relatively strong and not easily damaged during transportation.

The second is to reduce costs. Two sets together can save half the space, save packaging, and save shipping costs.

Finally, the production process is simple. During the production process, only one mosquito coil cutting machine is needed to make two pieces, which improves production efficiency.
