SULFUR used rubber: poison effect and buy/sell value

Used Rubber is a consumable ingredient that makes you Poisoned for 5 seconds when used, sells for 75 SulfCoins, and buys for 150 SulfCoins. Its in-game description sums it up bluntly: "A useful material, but probably not sanitary."

Stats at a glance

What Used Rubber actually does

Eating or using a Used Rubber applies the Poison status to you at strength +1 for 5 seconds. That makes it a poor pick as a snack, and the flavor text does not pretend otherwise. Its real value lies in its ingredient category: it is listed as a component in two crafting recipes:

• Anti-Poison Gum
• Energy Gum

Since it only occupies a single 1×1 inventory slot, it is cheap to carry back from a run even if you never intend to use it yourself.

Should you sell it or craft with it?

The buying and selling prices tell you the trading math directly: a vendor sells it for 150 SulfCoins but only pays you 75, so reselling is a net loss unless you found it as loot, in which case 75 SulfCoins is free money. If you cook or craft, holding onto Used Rubber for the gum recipes is usually the better call — Anti-Poison Gum in particular matters in a game where poison effects exist. Keep in mind that prices and balancing have shifted between patches; the 1.0.1 patch on 2026-10-29 already rebalanced other item prices, so treat these numbers as correct as of 2026-11-06.
