FAQ

Frequently asked questions about this product:

Where should the fabric for covered buttons be sent?

Please send it to the address below, including instructions such as the front/back orientation of the fabric.
4F Yamamoto Building
2-5 Kanda-Sudacho, Chiyoda-ku, Tokyo 101-0041
Attn: ApparelX representative

Why is the product image marked as "NO IMAGE"?

Items for which we did not receive permission from the manufacturer are marked as "NO IMAGE." We will continue negotiating to improve the customer experience, and once permission is granted, we will make them available.

Coated shell buttons for dyeing: There are white streaks on the back of the UST and USB series, but are they scratches?

It is a mark added to distinguish it from the manufacturer’s regular uncoated product number, so this is a specification.

How long is the lead time for covered buttons?

Although it depends on the quantity, if it is a small sample-sized order of around one product number, we can ship in about 2–3 days after the fabric arrives at our company.
Please contact us and consult with us each time, as the lead time depends on the quantity and type.

Please tell me the process, including how to specify the color when dyeing buttons.

・For color specifications, please send us an actual sample of the target item, or provide instructions using a YKK color, lining color number, etc.
・As for delivery time, it will take about 4 days for samples and about 1 week or less for mass production. *This may vary slightly depending on how busy the dyeing factory is.

The process is: after you place your order and provide the color instructions, we will dye the items and deliver them.
We will check the color here, but if revisions are needed, please send it back and we will make the corrections.

Would it be possible to request one of each color for the buttons?

We sincerely apologize, but for apparel production, we can accept it if it is for sample use; however, if the quantity is large, we may have to decline.

Is dyeing possible even for shell buttons that are not coated?

Yes, it is possible. However, an additional coating fee and coating lead time will apply. For details, please contact us from the Support page.

Is it possible to laser engrave buttons (add a logo)?

It may be possible depending on the type of button. If you would like a quotation, please contact us from the Support Page with the following details for your logo engraving request:
・button product number
・size
・color
・quantity
・logo data (please send Illustrator, PDF, or other data that shows the logo design)
We will contact you with details such as whether it is possible and a quotation.

*Laser engraving cannot be done on nylon, acrylic, or glass materials. Thank you for your understanding.

Can button samples be arranged?

We are sorry, but we cannot provide button samples free of charge. Orders can be placed starting from a minimum of 1 piece, so please place your order from each product page.

How long does delivery take if the buttons are dyed?

It varies depending on the quantity and number of colors, but if it is around 1 to 3 colors, shipment is possible in about one week.

White buttons look yellow. Depending on the size, buttons with the same color number may appear to be different colors.

For polyester materials and similar, if the item is white or a light color, the button color may discolor due to the production lot or aging.
If you absolutely need the colors to match, there are methods such as using a dyeable type and dyeing it to match the fabric color.
However, even after dyeing, the color may still discolor over time, such as after 5 to 10 years.

General Notes

Please confirm the following general notes regarding items at this site:

Zippers | Payment When Delivery Time Is Prioritized

We may shorten a longer zipper to the length you need. In that case, the unit price may change.

*** For bank transfers, please pay after the unit price is confirmed.

*** For credit card payments, please make an additional payment after the unit price is confirmed.

About Item Images

Screens cannot reproduce the actual texture or sheen of fabrics and other items, and colors may look slightly different depending on your monitor. We are working toward a world where physical sample books are no longer needed, but for bulk production orders we recommend purchasing a sample book to check the actual item.

Payment for Full-Roll Fabric Orders

The exact length of a full fabric roll may vary. We will notify you once the final length is confirmed.

*** For bank transfers, please pay after the final length is confirmed.

*** For credit card payments, we charge the confirmed length after the final length is confirmed (if it increases, we will ask for an additional payment; for payment methods charged when you place the order, we refund the difference if it decreases).
