＞＞What is Firefly Stone?＜＜
Firefly stones absorb light from the ultraviolet rays of sunlight or fluorescent lamps!
They release the absorbed light in the darkness!
＞＞Let’s make the Firefly Stone glow!＜＜
Place it as close as possible to a fluorescent lamp or desk lamp and wait for about 10 minutes.
Turn off the lights to make the room pitch black, or take it into a completely dark room.
The firefly stone will glow beautifully.
＞＞Common occasions for Firefly Stone＜＜
Surprise your loved ones at birthday parties, Christmas, Valentine’s Day, White Day, anniversaries, or other parties by serving it alongside a cake.
＞＞How to create a surprise＜＜
Pour juice into a glass that has been exposed to ultraviolet light, place it next to a cake, and turn off the lights to complete the surprise.
The glass containing the firefly stone will become a topic of conversation and a perfect item to liven up your party.
＞＞Tips for a successful surprise＜＜
Try testing it at the same time of day as your party!
The darker the surroundings, the more beautifully it will glow.
＞＞Q&A＜＜
Q. I left it in the sun for several days, but it won't glow at all!
A. Once the stone stops absorbing ultraviolet rays, the accumulated energy is released.
The release begins at sunset, so the accumulated ultraviolet energy is reset by the next day.
Expose it to sunlight and take it into a pitch-black room to see it glow beautifully.
*Please try this in a room with blackout curtains or similar.
Q. The product arrived, but it isn't glowing.
A. Since the product is kept inside a cardboard box during delivery, it has not accumulated any ultraviolet light.
Please expose it to a desk lamp or similar light source for a few minutes and try it in a dark place.
Q. It doesn't glow as beautifully as in the images.
A. For our product photography, we block all light with blackout curtains, turn off all fluorescent lights, and shoot in a pitch-black environment.
If you recreate a similar environment, it will glow as beautifully as it appears in the images.
