I ordered an advent calendar, the type you assemble yourself, and paid by Amazon Pay. On reflection, I decided to order two more for the grandsons, directly from the company. When we came to put one of them together, we realised the tabs weren’t long enough to go through the slots, and by glueing and hard work as a pair, we finally set all three up. Not sure if the little advent bits will fit in yet. After all that, the Amazon Pay didn’t go through ( no fault of mine) and so had to pay by phone to the company. The Advent houses look sturdy now, but clients need to be advised that glue will be necessary.
