This tool features a handle for a comfortable grip and various spatulas with the main sizes for smoothing silicone. The spatulas are interchangeable, and each spatula has 4 different sizes with embossed values. To change the spatula, simply unscrew the locking nut and replace it. To change the size on the same spatula, just loosen the nut without completely unscrewing it and turn the spatula to the desired size. It has a convenient hole for hanging and a raised grip for a good hold during use. If you have a multi-color printer, it is recommended to print the texts in a different color from the spatula to facilitate reading.
