Introducing the microlocs sizing tool! This tool is perfect for stylists who want to ensure that their microlocs are the proper size. With three unique ways to measure, you can be sure that you’re getting accurate measurements every time. The comfort finger grips make it easy to hold and use, while the keyring ensures that you always have it on hand when you need it. The front side has imperial (american) measurement sizes from 1/8" to 1/2", covering the most popular microlocs sizes. The back side has metric measurement sizes for our international customers. This product is designed and manufactured in USA with corn-based plastic (PLA). Polylactic acid or polylactide (PLA) is a polyester made from renewable biomass, typically from fermented plant starch like corn, cassava, sugarcane or sugar beet pulp. Due to the nature of the plastic, please do not expose to heat above 130 degrees fahrenheit or the tool may soften and deform. This is a 3D printed item, and as such the product you receive may not look exactly like the photos, but will be similar.
