This is a set of clear card cases and mask design stickers. You can use the balaclava stickers to cover the face on your driver's license or My Number card. The set includes 2 clear cases and 2 stickers. I bought these at a general goods store, but I have a lot left over, so I'm selling them. I'm listing only the number of items in stock, so if you need multiple sets, please use the bulk order option. *Please note that you cannot change the quantity after purchase. ■How to Use■ Place the sticker over the clear case, aligning it with the face photo. Please refer to the product images for details. *Please be careful not to stick the stickers directly onto your driver's license, etc. - Set Contents: 2 card cases, 2 stickers - Card Case Type: Clear card case - Sticker Design: Mask design Thank you for looking.
