Chalk Blocks 2-Pack

Harbinger Chalk Blocks offer a clean and dependable way to support grip during your workouts. Each 2oz block is made from professional-grade magnesium carbonate, a natural mineral known for its sweat-absorbing properties. By helping to keep your hands dry, these chalk blocks improve grip and reduce friction during training. Unlike traditional powdered chalk, Harbinger Chalk Blocks are less messy and easier to transport—ideal for gym use or tossing in your gear bag. Each block is crushable, so you can break it down to your preferred texture, whether you want a finer dust or a chunkier consistency. The magnesium carbonate formula also helps reduce friction, which can prevent discomfort such as irritation, blisters, or calluses during repeated movement. With the Harbinger Chalk Blocks, you get a practical, straightforward tool for maintaining reliable grip and chalk coverage, without the dust and hassle of powders. Whether you're lifting, climbing, or training, these compact chalk blocks are built for athletes who value clean performance and customizable grip.
