This is a set of 5 small LED flashlights. These are inexpensive products without a logo, but their performance is exactly the same as the logo-branded CREE UltraFire products. They can also use 14500 lithium-ion batteries, which make them even brighter than regular batteries. It's a great deal to buy them in bulk. Available in sets of 1 to 10. If you want a different number, please let me know in the comments. 1 for 600 yen, 2 for 1050 yen, 3 for 1450 yen, 4 for 1800 yen. From the 5th one, it's +300 yen per flashlight, up to a set of 10. They are reasonably priced, but they are bright enough. Please buy them in bulk for emergencies at home, or for your children's safety. They have a brightness of about 250 lumens in normal use. When the beam is narrowed, the light can reach about 300m to 400m. They are waterproof, so you can use them without worry on rainy days. They are convenient for outdoor activities, camping, and emergencies such as power outages. Please use them for children and women walking at night, and for crime prevention. Walking with a flashlight can signal that you are alert, which is a strong crime prevention measure.
