Biomarkers™ Plant Markers by MCG BioComposites, LLC - Plant markers for the eco-friendly gardener in mind! Made with proprietary blend of biomass and recycled plastics that is stronger and more durable!
What are BioMarkers?

The original plant marker was produced as an experiment in late 2009 to use our first formulated BioComposites material, which was corn cobs and recycled high density polyethylene, as a way to demonstrate to potential customers that our material was truly capable of processing by injection molding and also a viable substitute for petroleum based virgin plastics.

After introducing the markers to the market, it didn't take long for them to be a real hit!

Made from Recycled Plastic with Corn Cob Fiber.

       9.25" long, 1.875" x 2.875" flat marking surface
       13" long, 2.5" x 4.0" angled top and flat marking surface

Tough BioMarkers will last many seasons.

The weatherproof labels can be handwritten or laser printed and are pressure sensitive, so they are easy to remove when they do start to wear out. They remain in place and readable through all kinds of weather, but when it's time to peel them off, they don't leave a residue. You just clean off the marker and apply another label.

The markers come in three sizes, 9.25" long, 1.875" x 2.875" with a straight marker area and flat marking surface, 13" long, 2.5" x 4.0" with an angled marker area and flat marking surface and our new 24" markers also with a 30-degree angled marking surface measuring 5" x 4".
