It's paper, so maybe it can't be helped, but it was brand new and I was disappointed to see a small stain. I didn't go through the hassle of returning it, but it's fine if it deteriorates with use. I'm sure inventory management is difficult, but I hope Classico maintains its quality. I always use lab coats.
Small brown stains are inevitable with paper products, so please keep this in mind in the future. I have high hopes for Classico in the future and have deliberately given it a negative rating.

They just use the Gelato Pique name brand, but the quality is flimsy.
The print is on paper, so it will break if it gets wet, and the stickers cannot be reattached.
No matter how you look at it, it's not a product worth nearly 3,000 yen. I can't recommend it. The pricing is ridiculous.

The material felt a little cheap. It didn't feel sturdy.
