My Mother in Law gave us gift boxes for Christmas, and in them were these wonderful small tupperware type containers. After a while we realized they perfectly fit our yoto type RFID cards in them. I went to the dollar tree to find them, only to realize that they come in a three pack for $1.25 making each case $0.45. They are super durable, come in fun colors, and can be dressed up with fun decals or stickers if you’re so inclined. Check below for a 10% coupon code for a yoto player!
