the packs can be small, medium or large and manufacturable or bought from IM in 5's 10's or 50's for a range of prices. or perhaps manufacture the smalls and sell the medium and large in IM. can be manufactured in stacks like 50 at a time if you have all nessasary materials. pack will be tradable, stackable and reuseable. cept maybe the ones in IM since game need and always looking for a way to make money and wanting you to buy more)

small would have about 3-5 space
medium would have 5-10 space
and large 15 space

purpose of the packs:
you are able to trade items to a person in one go. or if you want to make a gift for someone and want to put all the items into one present instead of having to trade a bunch of items so this way you can also surprise them aswell.

here are some examples of packs you can sell:
make a killer pack and have all killer parts in it same goes for the other full sets you may have and want to sell together. (when pricing just add the individual item price together in 1 and minus 10% or w.e (example a killer part is 100k so a set pack is 475-500k get it?)

make a syrup or food pack (i don't need to explain just toss a bunch of food into it and sell 5 or 15 at a time)

kit packs: have raw material in a pack for making an item for people who have time to manufacture. so example christmas tree kit would have "50 vine grass, 5 cypress, 5golden flowers and 2 original rubber" in it ready for assemble

make a quest pack (i've always wanted to do this for my quest shop cause i run out of space) if doing quest for speed belt for example the pack would have all 4 or 5 snake skins already in it. if doing mushroom or flower quest in holy then you have all items in pack ready just open and quest completed. if doing angela quest, the pack would have the ladder, basin and blender in it.

thats another idea i was working on for manufacturable stuff that's TO LARGE you can turn into vouchers which can also be stacked eith those of the same kind. this would be useful for furniture shops and if you dont always have the space to make to carry and move around these items. click the paper open and you can drag the item in the box like with capsuling a vehicle (so yes both needs to be in your hand) and then it turns into a "manual blender voucher" or "large assembly tool voucher" or "garage voucher" well you get the point now they are compact, tradeable and sellable and can be stored.

and with these new vouchers here is another pack "home starter kit pack" have the basic tools in it or furnitures. you can have lots of ideas with this pack too:
tool bench pack. all tool bench tools
furnish pack. have hot kiln crystal furnish. clay kiln etc..
kitchen pack. have stove fridge etc...
bathroom pack. shower or ancient tub, toilet, sink elm tub etc..
bed room pack
sofa pack
storage pack. cabinets or wardobes
soda machine pack
shelve pack. for people starting a store
health pack. potion cabinet and medicine case prolly add a bonus item
