Mystery Bags Plugin

[Flufflings]

Hey guys, I am looking to buy a mystery bags plugin. Something like this:
https://www.spigotmc.org/resources/surprise-bags.21233/
It has some new features such as:
(No GUI reliance, items will be added to a virtual list)
(instead of basing it off of stack sizes for chance, chance would be defined when adding an item to the bag)
(Variant items that can be added to other items so let's say you have a shiny stick and a sticky stick, the sticky stick will drop 50% of the time when the shiny stick would've dropped normally)
(Better item meta saving)

PM me and we can work out a price.
