“The diorama depicts a birthday party with colorful decorations, presents and a table with cake that two child minifigures stand around. The pink wall can be reversed for a blue design instead depending on your preference, but both include a sticker of either a cake or text... More reading happy birthday.”

“The Birthday Diorama is also pretty cute and makes for a fun little gift, although its clear that World of Wonders is the far better choice to spend your VIP Rewards too.”
