I got the Doki Doki crates, and while being cute, the items they pick feel cheap and unsatisfying. Especially for the price that you have to pay for them. On top of that, they no longer offer free shipping so you have to pay a ridiculous amount for your box. As well, the boxes are frequently delayed and never on time. I had to wait 8 weeks for my July crate instead of 3-4 weeks.
Today, my subscription plan renewed for 6 months, and I tried to refund the subscription because of the absurd shipping costs. Of course the Japan Crate team did not give me a refund, and I am very disappointed and frustrated in the lack of empathy of the Japan Crate support team. I will never buy from them again.
If you are considering trying them however, first look at other cute kawaii crate options out there. There are MANY cheaper options that come with free shipping to any country! This business is such a rip-off.
