There's no coherent design here; few pieces look like they should come from the same set. It's also pretty idiosyncratic; the only piece with reindeer is "Santa's alien helper feeding Rudolph", with the Womdeer taking the reindeer's place in pictures with Santa.

The introduction is from the Easter Kiddy counters and references those pieces instead of the Christmas ones. It's mostly an annoyance, more than a problem.

They are $0.50 at time of writing, so they have that going for them. You could use them for a Christmas D&D game, for example, though they aren't cut out for a VTT. But for any other than the silliest use, you're going to end up using one or two and creating your own set of Christmas tokens. Even, or especially, for children, I'd want a more cohesive set of tokens.
