It seems you're asking about KIYOKA IR405 Toner Powder in a 500-gram package. However, there isn't a lot of detailed public information readily available for a product specifically named "KIYOKA IR405."

Here’s what I can infer:

• KIYOKA might refer to a brand or a specific line of toner products.
• IR405 could be a model number or a product series linked to the toner powder, possibly related to printer compatibility.
• 500 grams indicates the quantity, which is a relatively large amount, typically used for businesses or larger-volume printing needs.

If you're searching for this toner powder for a specific printer model or brand, it could be helpful to provide more context about the printer or system it is meant for (such as the make or model). You could also check with suppliers or online marketplaces that specialize in toner supplies, as they may carry this specific product.

Would you like help finding a supplier, or more details about toner compatibility?
