There are currently 4 lunchbox designs:
1. Classic - Just a metal lunchbox
2. Barweezle - a twitch streamers model made into a lunchbox design
3. Blue Sky - Just a secenic background
4. Nyan Cat - yes the meme

All 4 of these can be upgraded by crafting them surrounded by enderpearls where they will then hold 13 items per slot instead of 2. Allowing you to hold a stack+1 in amount. The boxes only hold food items. If there is food that it cannot hold let me know and MAYBE Ill try to fix that lol but Im a busy guy and jumping from project to project.

I made this mod for me and my friends to pair with the "Spoiled" mod so we can carry food and have them spoil less or not at all with a little extra balance. You CAN hold more than 1 at a time but that does decrease your slot count which can be used to carry other items. It is best to use them to just drastically slow down spoilage so it becomes less likely for people to carry a bunch on them because there food will still spoil in time.

Here are the containers you need to setup in the spoiled mod:
1. lunchboxes:barweezle
2. lunchboxes:barweezle_bigger
3. lunchboxes:blue_sky
4. lunchboxes:blue_sky_bigger
5. lunchboxes:classic
6. lunchboxes:classic_bigger
7. lunchboxes:nyan_cat
8. lunchboxes:_nyan_cat_bigger

Id like to make the mod more complex to cover edge cases more in the future but Im not sure if Ill ever figure that out myself.
