A set of four Christmas cards, plus envelopes. But these are quite special cards!
Each card is supplied flat, but when you squeeze the top and bottom edges together slightly, the card flexes and opens up. When you hold the card up to your eyes and look inside, you see a traditional Christmas scene in 3D! The town square is covered in snow, and there are children on sledges, horse drawn carts, and in the centre of the square a magnificent Christmas tree. Squeezing the card slightly allows you to adjust the focus.
All four cards have the same design.
The cards are 14.5 x 10 cm when flat, and each card has two integral lenses.
