The packaging with the frog (in Japanese, "kaeru") brings to mind the late 19th and early 20th centuries, when Japan created and offered to the world the mosquito coil and a way to spend a summer night without having the annoyance (and danger) mosquitoes bring. Almost 150 years later, things aren't all that different: mosquitoes are still a nuisance (at best) and Japanese katori senko (mosquito-repellent coils) like the Kaeru Jirushi Natural Insect Coils are the beset way to keep them away.
Made using only pure Dalmatian chrysanthemum pyrethrin (no chemical preservatives or coloring substances), each of the Kaeru Jirushi Natural Insect Coils will burn for about seven hours, allowing you to enjoy a full mosquito-free night. Since this is a two-box set, you get 60 coils, which means that you can forget mosquitoes for two whole months! And of course each box contains a metallic stand so you can start using your all-natural coils immediately!
