<b>[Product Information]</b><br>
<ul>
<li>Great for extreme outdoor conditions because it can withstand harsh weather conditions and months of jobsite wear.</li>
<li>Flip-cap keeps the chalk in the bottle where you want it and stops it from spilling out in areas that you don't.</li>
<li>Flip-top cap also seals the chalk in an airtight chamber, keeping out moisture and reducing the risk of clumping.</li>
