Is it amazing even though it is 100 yen? Introducing Daiso's "Dimmable Touch Switch Light" whose brightness can be adjusted steplessly.
A palm-sized LED light that illuminates the top. The body color is available in white and black. Required power is 3 AAA batteries (sold separately).
Turns on / off when you touch the power mark on the front with your finger. Press and hold to increase or decrease the brightness. The brightness of the previous use is memorized, so if you want to use it with a fixed brightness, you can operate it with just an on / off touch.
This is useful because it is stepless dimming! I can't think of it at all, but I think it's amazing that this operation can be done for 100 yen. Please check it out if you come to the point of use.
