It seems to be useful for going out during Golden Week. I found a "clip" that can be expected to have an insect repellent effect.
This goods named "Aroma Fragrant Magnet Clip". The scent "Citronella", which is said to be disliked by insects, is kneaded in, and when the seal is opened, a refreshing scent spreads. It can be folded in half with magnets on both ends, and can be attached to hats, collars, sleeves, bags, etc. wherever you like.
Using magnets on both ends
You can put it on your hat
You can put it on your sleeve
It's an easy-to-use item, but since it uses magnets, you need to be careful not to bring it close to magnetic cards or precision equipment. Also, since it has a strong scent, it seems better to refrain from using it in places with many people such as trains and put it in a bag that can be sealed.
The selling price on various mail order sites is around 500 yen. It is also sold at general stores. The scent lasts for about a week, so it can't be used for a long time, but why not add it as one of the insect repellent measures?
