This is a "Suffocation Warning Label" for Amazon FBA shipments. #Yuunagi Warning Label Set There are various ways to refer to these labels, such as warning labels or suffocation warning stickers. These are required when shipping to FBA and you see instructions like "Use bags with a warning mark indicating the danger of suffocation." These warning labels are to prevent the danger of suffocation, as small children may swallow or put the bags over their heads. Apply directly to the packaging vinyl. The content is standard. The size of one label is 66mm x 34mm. There are 24 labels per sheet, and this is a set of 20 sheets (480 labels). I have a large stock, so I will sell them in smaller quantities to those who need them. I also have other warning label sets available, so please feel free to purchase the number of labels you need! #Yuunagi Warning Label Set *Please refrain from price negotiations (*- -)(*_ _)Pecori (bowing)*
