[Question]Trainer's 99 bag slots

Does the 99 bag slots hack that appears on almost every trainer realy work?

I mean, does it really store any item after the 20th slot even after relogin?

For exemple if i have 20 items (bag full) and use the hack and accept\buy another item, do i DC? does it keep the item after logging out? (making 21\20 slots) Does it disappear after logging out but reappear after i use the hack again? Or does that 21st item just vanish after Logging out?

I'm sorry if the question is confusing, english is not my original language

Thanks in advance

I think you should try that by yourself. It either removes your item after relog or gives error message while ex. buying an item, I assume. Or it possibly says that your inv is full.
