The versatile formula is designed for both interior and exterior applications. Each bottle of IRWIN STRAIT-LINE marking chalk features a flip-top cap that is specially engineered for an airtight seal that keeps moisture out and minimizes clumping. From the Manufacturer Chalk Refill, 8 ounces of blue chalk refill for all reel type chalk line boxes, packaged in a plastic squeeze bottle with fast-fill spout, and snap cap to prevent spilling and moisture in chalk. Irwin tools are made of only the finest materials, manufactured to exacting tolerances. Review: Great snap line refill at a super price - Great item at an awesome price. Works as intended. I don’t need it to be permanent but it lasts long enough for its intended use. I recommend using this product. Review: Excellent for tinting drywall mud - I use this to tint drywall mud and it works extremely well. A little goes a long way when mixing into drywall mud. My advice is to add slowly while mixing. This product doesn’t require you to add more water to your mud. This chalk will not affect your mud’s ability to stick. For all purpose mud, this is a great addition to help when doing a second round for skim coating. Most PVA primers will hide the blue color in one coat as long as you keep it a lighter blue. ## Features - Use this marking chalk to provide temporary marks with great visibility - This marking chalk is designed for both interior and exterior use - STRAIT-LINE marking chalk comes with a flip-top cap for an airtight seal that minimizes clumping - Color: Blue - 8-ounce weight ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00002N6RH | | Additional Features | Refillable | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #55,181 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #25 in Measuring & Layout Chalk Lines | | Body Shape | Round | | Brand | IRWIN | | Brand Name | IRWIN | | Closure Type | Snap | | Color | Blue | | Customer Reviews | 4.4 out of 5 stars 796 Reviews | | Drill Point | Chalk | | Global Trade Identification Number | 00024721500076 | | Grip Type | Flip | | Hand Orientation | Ambidextrous | | Included Components | -- | | Ink Base | Water | | Ink Color | Blue | | Item Dimensions | 5.91 x 3.15 x 7.87 inches | | Item Height | 7.87 inches | | Item Type Name | --- | | Item Weight | 0.1 Kilograms | | Line Size | 2mm_and_above | | Manufacturer | AMEX9 | | Material | Chalk | | Material Type | Chalk | | Model Name | ---- | | Model Number | 64901 | | Pattern | None (or) Not Applicable | | Recommended Uses For Product | Home, School | | Style | utilitarian | | UPC | 024721500076 | | Unit Count | 1.0 Count | | Writing Instrument Form | Chalk | ## Images ![Irwin Tools Strait-Line 64901 Chalk Refills - Image 1](https://m.media-amazon.com/images/I/61ifMLFSzkL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great snap line refill at a super price *by B***R on May 15, 2025* Great item at an awesome price.
