Around 2 years ago we changed the yellow used in all of the 2mm & 4mm static grass ranges, with great success, resulting in more natural looking blends.
Due to popularity we maintained the old orange-yellow in wild meadow and wild grassland 4mm tufts. We have now decided to change these remaining 2 tuft colors (they will now match the static grass blends) as it is not financially viable to restock the old yellow for only 2 colors of 4mm tufts.
We have temporarily place these out of stock, new images will be up and stock available in a few days. This includes the x91 range as 4mm is included on each sheet.
