You will be neomailed if you win something. The time they announced is 6 am and 6 pm everyday. I won once (the Kentari Spyglass Stamp) and still continue to wish everyday.

can we sell the item?

Yes =D

Thanks for the information! I will try to do this everyday now.

Just spent about 1k at the wishing well! Wishing for random stuff XD

I probably start to wish 10 times each time. Mostly Bag of Peanuts for now to get avatar items (and it's the most expensive), after that, I will try some stamps for my album...

My 3rd Bag of Peanuts and my 4th win. I wish about 10-15 times each time with 21-25 NPs each...

Wow! You are lucky.

Lucky ducky! I just want those things I'm gonna go visit the wishing well...

you keep wishing and someday it's yours. It doesn't cost much so make it your dailies...
