    No issues: compact and easy to use. Does the job with good results. I also have the medium file. I need to get the narrow file next.

    Brilliant product

    Hosco products are of incredible quality! This is a top notch product that really helped speed up the otherwise laborious task of crowning frets! Does stainless steel like butter. I hope they last for a good long while! I also want to commend PLT for their amazing customer service experience and quick shipping to Sri Lanka! Cheers!
