Mule Oil Foot Mask 1 Use 5 Pairs Pack – Exfoliates Dead Skin and Calluses

[Contains High-Quality Domestic Mule Oil] Contains "mule oil," which is very similar to human sebum and is known as an all-purpose oil.
[Foot Exfoliating Product] The sock-shaped plastic bag contains a solvent primarily made of AHA, which helps to easily peel off excess keratin from the soles of the feet after soaking.
Similar to facial exfoliation products, but since it soaks for about 40 minutes, it penetrates deeper into the thicker keratin on the feet, effectively removing calluses without any pain.
