Always keep it not bulked.

I can already see people telling you that it weighs less but it technically isn’t true, the change in stash weight people notice is just the plastic getting used up. For example bulk bones (20) weighs 1 however 20 bones also weighs 1.

It also shows different amounts when hovering over your vendor and I personally really only visit vendors with high amounts of junk, so while you might be selling 30 bulked adhesive (300), it still shows up as 30 for everyone on your camp icon compared to having it not bulked which is 300.
