Please clean the adhesive surface and try again.

If the issue continues, please contact our customer support team.

After each use:

  1. Gently wash the adhesive surface with mild soap and warm water.
  2. Rinse thoroughly to remove residue.
  3. Allow it to air dry naturally.

  • Alcohol or harsh cleaners
  • Towels to wipe the adhesive surface

With proper care, Niidor adhesive bras can be reused multiple times.

The lifespan depends on usage frequency, cleaning routine, skin condition, and maintenance.

Returns, Exchanges & Refunds

Eligible return requests and after-sales claims for defective, damaged, incorrect, or missing items must be submitted within 30 days of delivery. For personal-reason returns, the original factory seal or shrink wrap on the product box must remain completely intact. Once the original factory seal or shrink wrap has been opened, cut, torn, or removed, intimate products are not eligible for return or exchange for personal reasons.

Personal-reason returns may be eligible within 30 days of delivery only if the original factory seal or shrink wrap on the product box remains completely intact. Please contact Niidor Customer Support before sending any return.

For hygiene and safety reasons, adhesive bras, nipple covers, bra inserts, and other intimate products are not eligible for return or exchange for personal reasons once the original factory seal or shrink wrap has been opened. This restriction does not apply to confirmed product defects, damaged items, incorrect items, missing items, or other issues caused by Niidor.

If you receive a defective, damaged, incorrect, or missing item, please contact us within 30 days of delivery. Please provide your order number, a brief description of the issue, and clear photos showing the product and the reported problem. If photos are not sufficient to confirm the issue, we may request a short video. Once confirmed, Niidor will normally prioritize replacement or reshipment. If replacement or reshipment is not reasonably available, a refund may be provided for the affected item.

For eligible personal-reason returns, customers are responsible for return shipping costs and related return charges. For confirmed issues caused by Niidor, we will provide an appropriate after-sales solution based on the specific situation.

Size or color exchanges for personal reasons are only available if the item meets the applicable return eligibility requirements, including an intact original factory seal or shrink wrap. Please contact Niidor Customer Support with your order details for assistance.

Once an approved refund has been processed, it will be returned to the original payment method. Refunds typically appear within 5–10 business days, depending on your bank or payment provider.

If tracking has not been updated for an extended period or shows an abnormal status, please contact the corresponding carrier directly for further assistance. If tracking shows Delivered but you cannot locate your package, please contact the last-mile carrier and open a missing-package or delivery investigation. Keep the case, claim, or investigation number. If the carrier requires action from the sender or the issue remains unresolved, contact Niidor with your order number, tracking number, and carrier case or claim number.

No. For hygiene and safety reasons, intimate or skin-contact products with the protective film removed are not eligible for return or exchange for personal reasons. Confirmed product defects, damaged items, incorrect items, missing items, or other Niidor-responsibility issues are handled separately.
