SPECIAL ANNOUNCEMENT: COVID-19: 

Dear valued customer,

The current situation caused by the COVID-19 virus has multiple consequences in all aspects of our daily lives. It presents to us, as a company, with major challenges regarding both our customers, and our employees who remain our top priorities. It’s not just the playgrounds and public areas, restaurants, and theaters that must shut down, but also the companies, their partners, and suppliers that need to shoulder a tremendous amount of responsibility these days.

As your partner, we take our part in your supply chain very seriously. Therefore, please be informed that MH&W International is doing everything within its power to ensure minimal disruption in your supply chain caused by COVID-19. Due to possible disruptions in our own supply chain, and unpredictable circumstances with our employees’ families, please be aware of possible delays in our deliveries at least for the upcoming weeks.  Our warehouse is in full operation with a reduced staff capacity, to follow guidelines.

Following government declaration, your MH&W team is working out of our home offices.  Office phones are automatically routed to either our home office or cell phone lines.  In the event we cannot answer your call, please leave a message, and we will respond back in a very short period of time.

You may also send an email to [email protected] and it will be routed to the appropriate staff member, or directly to your account representative.

We kindly ask for your understanding and wish you all the very best for you and your families. Please do not hesitate to contact us at any time should you have any further questions.

Sincerely,
Your MH&W International Team.
