Bulk glass

Bulk glass is a junk item in Fallout 76.

Characteristics
Combines ten units of glass shards into a single item. This does not affect the total weight of the glass. Unlike the raw material, bulk glass is able to be sold to vendors.

The perk Pack Rat seems to interact strangely with this item. With rank three Pack Rat equipped the weight of ten glass shards is 0.15 while the weight of one bulk glass is 0.19, creating an unexplained .04 increase in weight when bulking.
