These are possible dupes to Orly's popular Glowstick.
Very good alternatives if you can't get hold of Glowstick and one is a cheaper option as well.
On the picture from left to right:
Depend is the cheapest one but also the smallest bottle.
They are all neon yellow but there is a hint more green in them from left to right. Glowstick is the one with most green in it.
But the difference between them is tiny.
I think Rare has the best formula so Rare is my no one choice for neon yellow! :)
