Guys and gals don’t always like the same things do they although there is nothing to stop you picking a card from the list for one gender to send to someone else. With a sister who would not wear a skirt only a kilt, because tomboys wore the same things as men I can understand why things are not always what they seem.
You can choose from a number of different wooden templates mostly different forms of transport. They come with a printed sheet with “happy birthday” words that you can stick on inside or outside. There are 3 A6 sized cards and with matching envelopes in a pack. A6 is about 10 cm by 13 cm i.e a quarter of the size of A4.
There are a mixture of cards in the pack, some portrait some landscape while some white some coloured. These packs are mainly pastel colours and are more likely to be blue pink than pink.
