These are not two sizes of the same thing. They share a foundation. They do different jobs.
The shared part
Both start with grass-fed tallow and honey.
The jar
The jar adds olive oil. It’s for dry-feeling skin on your face, hands, and anywhere else that feels tight. Warm a little and press it in.
The slider tin
The slider tin holds the chapstick with beeswax. It’s for dry lips. Keep it in a pocket and use it when your lips feel dry. Not for the eye area.
If you only get one
If the dry spot is skin, get the jar. If it’s lips, get the slider tin. A lot of people end up with both. That’s a habit, not a rule.
Two products, each with a small natural ingredients list.
