Founded in 1955, Ishihara Shoten is not as well-known as a first-tier cosmetics brand, but its suppliers are the same as big brands such as Shiseido, Lancôme and Estee Lauder, and it is Yukiya Chemical, which has a 70% share of the makeup sponge industry, and the price is affordable, with a single sponge priced between 10 and 20 yuan.
 
Synthetic rubber material cosmetic sponge was first introduced by Yukiya Chemical, and gradually replaced natural rubber, which is prone to allergies, and became the main material in the cosmetic sponge industry. Among the more than 30 cosmetic sponge products in Ishihara store today, they are basically made of styrene-butadiene rubber (SBR) or nitrile rubber (NBR), and there is only one 6-piece natural rubber puff, which costs about 27 yuan and can be used as a daily powder puff replacement.
 
Nitrile butadiene rubber (NBR) is the main product of Ishihara Shoten's makeup sponges, and big brands such as Lancôme and Shu Uemura also use NBR to make sponges. However, while most of these big-name makeup sponges have irregular three-dimensional shapes such as gourd-shaped, Ishihara Shoten NBR makeup sponges are only a common flat design, which is not as fast as makeup application and taking care of facial details.
 
Another disadvantage of NBR cosmetic sponge is that the texture is hard, and the skin-friendly performance is not ideal. For those who have high requirements for skin-friendliness, it is recommended to choose Ishihara store SBR material makeup sponge, the softness of the material is second only to polyurethane (PU), there are different shapes such as triangle, diamond, square, etc., suitable for makeup on the details of the face, the price of 30 pieces is less than 30 yuan, and the price is also quite affordable.
