I love the look of this Advent calendar Puzzle Box from Party Pieces, and it's down in price from £22.99 to £14.49 right now.
We love Advent in our house, and have a gorgeous wooden Advent calendar which was a gift from Granny when my lads were tiny. It's one of the traditional wooden ones with a little drawer for each day of Advent so that you can pop a treat or a surprise in each one.
When I'm organised enough I love planning a festive activity for every day of Advent - I scribble down a description on a piece of paper, roll it up and pop it in the drawer, then let the kids discover what that day's festive fun will be each morning. Sometimes it's something quite elaborate like a Christmas craft activity but other times it's something as simple as instructions to watch a family Christmas film and sup hot chocolate while we do so!
It looks as though you could do exactly that with this Advent calendar Puzzle Box - the cubes fit together to make four different Advent-themed puzzles but they're also numbered and can be filled with a chocolate, treat, or Advent craft so it's basically an Advent calendar, Christmas puzzle and craft session all rolled into one!
Standard delivery from Party Pieces is £3.95.
