Smart Callus Care to Maximize Performance

Calluses aren’t the enemy. Neglect is.

The SandBar 4" Quickie Callus Kit is built for athletes and musicians who rely on their hands and fingers to perform at their best. When finger calluses get too thick, too dry, or too jagged, they don’t protect you—they rip, split, and kill your grip.

Quickie is designed to maintain the callus where it belongs—strong, smooth, and functional—without stripping away your hard-earned protection like razors and harsh removers.

This is callus care that keeps sensitivity and control intact—so you can train harder, play longer, and perform better.


Why It Works

Cylindrical Precision Design

The rounded shape contours perfectly to your finger calluses, targeting the primary pressure point while helping maintain finger sensitivity and control.

Compact + Always Ready

Small enough to live in your gym bag, instrument case, truck, or pocket—so you can fix problem spots the moment they show up.

Quick, Safe, Athlete-Grade Grit

Smooths rough edges and strengthens calluses without over-filing, keeping the protective layer intact and reducing tears.

Callus Salve Included

Hydrates and protects callused skin so it stays flexible, healthy, and resilient—especially after training or playing.

Built to Last

Solid aluminum construction engineered for daily use, designed to hold up 1 year+ under real work.

FAQs

The Original 8" SandBar is intended to address all of your calluses at the same time. The Quickie is perfect for addressing individual calluses, especially on fingers.

Right after using your SandBar. Moisturizing dead callused skin doesn’t do anything for you. First, file off the dead skin. Then apply the salve to nourish the healthy callus, keeping it pliable and ready to work.

Every single day. Everytime you put friction and/or pressure on your skin, calluses build up. Your hands and feet have a high rate of skin cell turnover. The top layers dry out and build up faster than the rest of the body’s skin. Every rep, every step, every time you work hard with your hands and feet, you are creating build up. Manage your calluses by checking on them and filing them on a daily basis. Think of your SandBar as an industrial toothbrush for your calluses.
