We are sorry, but we cannot respond to your request.

Are the products sold in other stores the same?

It is a product of another company.
Our products are sold at TMC ShopifySHOP under the trade name "MASKBONE".
Everything from production to packaging and shipping is done at a factory in Japan.
We are not aware of the materials used in other stores' products, but our products are made of durable materials.

Can it be attached to a cloth mask?

It cannot be used with anything other than a standard non-woven mask.

Is it possible to purchase a set of 10 pieces, for example, 5 pieces of 175mm and 5 pieces of 145mm?

We are sorry, but we cannot respond to your request.
Each 175mm and 145mm is packaged in a bag of 10 pieces, and both products are only sold in packs of 10 pieces, as they are sanitized and inspected by the packing factory.

How long does each bottle last?

It is difficult to answer this question as it depends on the usage conditions.
In-house evaluation showed no problems after one or two months of use.
However, the products are plastic consumables, so if the hooks become loose, replace them with new ones.

Can I wash it and use it again and again?

You can use it.
The product is made of plastic, making it washable in water and easy to clean.
It can be kept clean and used repeatedly.

Which is the correct orientation of the central projection up or down during installation?

It does not matter whether it is oriented top or bottom.
The protrusion in the center is necessary for comfortable use due to design and manufacturing and does not affect the function.

There is no space in the mask when the product is attached, but is the position of the attachment bad?

It is expected that there will be individual differences.
The appropriate position of the mask should be found by the individual, as there are individual differences in the type of mask and the shape of the face.
If the mask does not fit in the center, we recommend shifting the position of the mask up or down slightly to find the right fit.

Why is there variation in the shape of the curves in the 175 mm size product?

Some of the curves may change shape when the product is packed in bags, so there may be some variation.
The curves are designed to be arbitrarily set to a certain degree and can be adjusted by customers themselves by widening or narrowing them to the optimum width.

Do you plan to make your products in colors other than white?

There are currently no plans to make anything other than white.
We have had more than a few inquiries for more color varieties.
We take this as very valuable feedback, but we have not yet decided on the production of the product.
