These items are from the Showa era. This is a set of 4 items. Kitty tile, perfect for handicrafts. There is wood on the back, as shown in photo 3. The Kitty with the blue string is a premium item, and it makes a clicking sound when you press the back. There's also a clip and a clear house. Simple packaging and shipping. m(__)m Please understand that these are old items. If you have any questions, please comment or request additional photos. (^^) Sanrio Premium Showa Retro
