XP Potions and Third Eye stacking ?

[Smilo 109]

I saw in coin shop that 24 hours xp potion is stackable. Does that mean only in inventory or can I use 2x 24 hours to get 48 hours buff ? 

If yes does that work with 1h or 3h Potions and Third Eyes too ?

what I remember that this option was possible but now it is not.

but the word "stackable" remained on the item  ?‍♂️ 

a few years ago it was possible to see chars with 100 hours of xp pot.

It was because, some years ago, when you got to lv 100, you received 7 days of xp up.
