  • PWMG is still operating. We have been working in a virtual environment for several years now and are still here to answer questions, accept orders and otherwise help you as needed.

  • Communications: In light of our virtual work environment, we utilize an answering service to answer our calls. This service has shut down it's offices, but is still operating remotely. We may not get messages as quickly as we'd all like, but we will get them and will call you back.
         Alternately you can call us at phone number 313.300.0134 or send us an email at pwminc @ or lmarino @ (we suggest using email)

  • Shipping: Although we are here take an order, our inventory is stored in an off-site location; our respective states are under "stay at home" orders and are requiring non-essential businesses to close - our inventory may not currently be accessible to us. We'll ship your order as soon as we're able.

We're all eagerly waiting for the time when we can get back to business as usual, but until then we appreciate your patience and understanding.

Best Wishes,

Paul W. Marino Gages, Inc.
