This is a "Suffocation Warning Label" for Amazon FBA shipments. These are also known as warning labels or suffocation hazard labels. They are required when the FBA shipment instructions state, "Use bags with a warning mark indicating the danger of suffocation," etc. These warning labels are to prevent the danger of suffocation for small children who may swallow or put the bags over their heads. Apply directly to the packaging vinyl. The content is standard. Each label is 66mm x 34mm. There are 24 labels per sheet, and this is a set of 10 sheets. We have a large stock, so we will sell them in smaller quantities to those who need them.
