The art style looks basically pastel colors, and since this anime short is for everyone of any age, it's also appropriate.

I've watched a lot of anime (probably not as much as some/most), but I can safely say that this was a great experience.

It's different. It's magical.

I mean, it's such a cute concept involving zippers and family!

The short is worth approximately 10 minutes of your time if you want something a little new to your diet of anime.

EPISODE 02: So now there's an Episode 02 for this "series".

I will be keeping the score of 10 for Fastening Days.

Having just recently been introduced to the anime world. All I see are high school animes and more high school animes. And then some more. And after that I see shows like Zankyou No Terror which also shows high school students capable of destroying the world (mind you they were pretty old, but they still went to a high school). And then I see this show which I thought I would give a try since it was only one 11 min long episode. Considering that most of the YouTube videos that I watch are also approx. 10 mins long, I figured I might as well read more
