What it is
This carbonated*1 bath ball envelops your skin in fine bubbles. Enjoy a relaxing bath time with the fizzy sensation of dissolving in the bathtub. Formulated with corallite*2, a natural mineral derived from coral and rich in calcium and magnesium, it supports skin moisture. This item, reminiscent of a winter solstice yuzu bath and its comforting aroma, makes a wonderful gift for yourself or someone special. *1 Sodium bicarbonate (base) *2 Calcium carbonate, magnesium carbonate (all moisturizing ingredients). The scent combines the fresh aroma of yuzu and orange with refreshing rosemary for a gentle, warming fragrance. The design features a circular design that mirrors the roundness of a yuzu, with a soft, fading gradient that fades away as it descends. It evokes the image of the warmth and scent of yuzu floating in the water on the winter solstice, dissolving into the water.

I tried the Yuzu Healing Bath Ball. When I put it in the bath, the soft, gentle scent of yuzu spread, and it was more relaxing than I expected. The scent isn't too strong, so it's perfect for when you want to take a long, relaxing bath.
The fizzy packaging gives it a special feeling, and just looking at the box is satisfying. The carbonation is amazing, and it's so fizzy and completely different from the bath bombs kids get. The scent is a gentle yuzu scent, soothing, and while soaking in it, I couldn't help but think, "Ah, I'm so happy..." This is a bath bomb that I'd like to use as a monthly treat, and I think it would also make a great gift.
This is a limited edition Osaji product, and it's a yuzu bath bomb. I was curious, so I bought two. It's quite expensive for a bath bomb, so I limited myself to two. I used it as a reward for hard work. I put it in the bathtub right before getting in the bath. While the bath bomb was fizzing and dissolving, I was hit with my favorite yuzu scent, which was a blissful experience. The fizzing sensation of the yuzu scent and the bathwater felt like it was fizzing away my fatigue, which was really refreshing. (I'm not sure if this is the correct way to use it, though...) The bathtub turned a very light yellow? Yellowish-white? The scent didn't linger much after the bath bomb completely dissolved, and I had to sniff carefully to get a faint hint of yuzu. As a yuzu lover, I wished the scent had lingered longer. So, adding it just before getting in the bath was a great decision. In terms of satisfaction per unit price, I'd give it a 3 to 4 star rating.
I bought this for my weekend bath time. The scent is not too strong and is soothing. The water becomes a little thick and my skin feels moisturized.
