This is a set of 10 "Japanese candles used in time" that allows you to enjoy a relaxing time for 20 minutes. Because it is designed to burn for about 20 minutes with one bottle, it is easy to use for scenes where you want to spend a cohesive time with yourself, such as meditating, reading, or changing your mood. The raw materials are 100% plant-based raw materials, including goby wax, which has been used in Japanese candles for a long time. It is a Japanese candle that does not use petroleum-based raw materials such as paraffin, contains little soot, and can be used indoors with peace of mind. Japanese candles inherit the traditional technique of designing the burning time by adjusting the thickness and length. Utilizing the wisdom of the manufacturing site that has made candles according to the different times of reading and meditation at each temple, we designed it in an easy-to-use time unit of "20 minutes". The calm gray box was commissioned by a long-established box manufacturer in Kyoto. This set is easy to handle as a gift and is easy to introduce to general stores, accommodation facilities, retreats, workshops, and other experiential purposes.
