Of course care is needed so as to not damage or bend the tool into an incorrect position as it will become useless to the aviation maintenance professional.   We recommend that you keep your borescope guide tube in a clean and safe place as to avoid damage or contamination from entering the tube itself.   In some cases we can offer the borescope guide tube in connection with a borescope rental.
