Black Dirt Bags
Stone In the Buff
Unit Quantity
I'm the original comPOST Pack - a certified home compostable, fully biodegradable mailing satchel partly made from plants. I have a lovely, matt finish with printed graphics as per the image gallery. I'm flat (i.e. no gusset, but some stretch) with a flap and self-seal strip.

XXL now comes in a 63um thickness. This allows slightly more light through but the bags remain opaque and still provide excellent protection for your products.

Black Dirt Bags come in all sizes, others as follows: 

  • Stone In the Buff: Large, XLarge

There's been a little whoops on some of our LLarge Black Dirt Bags and they have a minor print flaw (see image in gallery). These bags still behave exactly like our other mailers but you can bags some now at a discount. LLarge mailers without print flaws are also available. 

Check the Sizing Guide in the image gallery as the bag thickness and number of seals vary by size. 

I behave just like a plastic satchel except when left in nature! In a home compost I will biodegrade in 3-6 months and can also be commercially composted. Find out how. Labels stick to me no problem*, and I'm waterproof and strong. Better. Right.


  • Only our Black Bags are completely opaque, all other colours are slightly transparent.
  • *We do extensive QA testing with our own labels and others, but can't guarantee that ALL labels will to stick to these mailers
