Magnetic Pen Holder

You can use this holder to keep a pen handy anywhere you have a metal surface. Works great on the fridge, laundry appliances, in the garage, workshop/woodshop or home gym. The 10.6mm holder will hold small pens such as a Bic or Papermate Flexgrip (provided they have either a cap or a pocket clip to stop them from falling straight through).The 13mm holder will hold pens up to and including a sharpie size. Three recesses on the back will accept 10x3mm magnets or smaller. The center recess is deeper to reduce the chance of the magnet becoming a central pivot point, keeping the holder more stable. I'd recommend a dab of glue to keep the magnets in place; I left the tolerances loose to avoid the frustration of magnets not fitting.
