12 Sticker Christmas cards

This fun box comes with 12 Christmas cards, in two different designs:

1. Mary, Joseph and Jesus in the manger
2. Shepherds and angels on the hillside

The picture on each card is completed by adding 4 stickers.

But the question is:

Will you stick the stickers before you send the card?

OR

Will you send the stickers with the card to the person who receives it to do the sticking?

All the cards come with envelopes.
