Glass Bottles is an Item that can only be found in the form of Golden Pupa loot. Upon being picked up, all of the player's current and future Cows and Grass-Fed Cows will be able to be milked for Cashews. This comes in the form of a floating Milk bottle above the given Cow's body that needs to be collected by walking into it or by using the harvest key. A basic Cow's Milk sells for 60 , while a Grass-Fed Cow's Milk sells for 90 . Because of this, a Grass-Fed Cow still remains more valuable than a basic one in every regard. Glass Bottles is also impacted by Luck.
As stated, the player's Luck value affects Glass Bottles. This means that Cows and Grass-Fed Cows will be more likely to produce Milk every 20 seconds. Each whole point of Luck is scaled by 0.5 in determining the new probability of Cows granting Milk after each 20 second cooldown period.
Compared to other Cow and Grass-Fed Cow related Items, Glass Bottles is the only one that can make these Farm Animals a direct source of profit. This can make it more valuable than other Cow Items in that regard. Furthermore, when compared to other means of gathering Cashews from Farm Animals, Glass Bottles possesses the second and third highest value per collectable. For clarification, Chicken Eggs sell for 10 , Turkey Eggs for 40 , and Truffles for 200 . As shown, Nasal Spray is directly more valuable numerically than Glass Bottles. Due to this, Nasal Spray may be more preferable than Glass Bottles because of the higher value per collectable. However, unlike Nasal Spray, Glass Bottles is not tied into Cows preforming their chores. This means that players can potentially obtain more individual collectables than Nasal Spray can with Pigs or Hogs.
