First-time users may notice a mild foreign-body sensation and can begin with shorter wearing periods before gradually increasing usage time.<\/p>\n\t<p>If you continue to experience pain, pressure, rubbing, or frequent loosening, recheck the size and wearing angle.<\/p>\n\t<!-- Adjustment -->\n\t<h2>Can Gnasal Be Adjusted?<\/h2>\n\t<p>Gnasal features an adjustable internal support design. Small, gradual adjustments can be made according to your nasal shape, nasal width, and wearing comfort.<\/p>\n\t<p>Adjust the product gently. Avoid repeated excessive bending, pulling, twisting, or sharp-angle folding. Damage caused by improper use or excessive adjustment may affect warranty or after-sales service.<\/p>\n\t<!-- Taiwan Exchange -->\n\t<h2>Size Exchange for Taiwan Orders<\/h2>\n\t<div><strong>The following size exchange policy applies only to orders in Taiwan.<\/strong>\n\t\t<br>For international orders, please refer to the \u201cInternational Orders &amp; After-Sales Service\u201d section below.<\/div>\n\t<p>Customers in Taiwan may request <strong>one size exchange within 14 days of receiving the product<\/strong> if the original size is not suitable.<\/p>\n\t<p>Size exchange and return\/refund are separate after-sales services and cannot both be used for the same purchase. Round-trip shipping costs for a size exchange are the customer&#8217;s responsibility.<\/p>\n\t<p>To request a size exchange, please contact Gnasal customer service first and provide the following information:<\/p>\n\t<ul>\n\t\t<li>Purchase channel or platform<\/li>\n\t\t<li>Order number<\/li>\n\t\t<li>Name and contact information<\/li>\n\t\t<li>Original size purchased<\/li>\n\t\t<li>Size you would like to exchange for<\/li>\n\t<\/ul>\n\t<p>After confirming your request, customer service will provide instructions for returning and exchanging the product. <strong>Please do not return the product before contacting customer service.<\/strong><\/p>\n\t<div><strong>Please note:<\/strong> As Gnasal is a personal-use hygiene product, exchange eligibility may be affected if the product has been damaged through improper use, excessive adjustment, or other handling beyond normal fitting and trial use.<\/div>\n\t<!-- International -->\n\t<h2>International Orders &amp; After-Sales Service<\/h2>\n\t<p>Size exchange, return conditions, shipping costs, and after-sales procedures for international orders may vary depending on the destination country or region, sales platform, and shipping method. Therefore, the Taiwan size exchange policy above does not automatically apply to international orders.<\/p>\n\t<p>For international purchases, we strongly recommend completing the measurement steps on this page and checking the S\u2013XXL size chart before ordering.<\/p>\n\t<p>If you have a sizing or fitting issue after receiving your order, please contact Gnasal customer service first and provide your country\/region, purchase platform, and order number. We will assist you according to the after-sales policy applicable to your order.<\/p>\n\t<!-- FAQ -->\n\t<h2>Gnasal Size FAQ<\/h2>\n\t<h3>What If I Am Not Sure Which Size to Choose?<\/h3>\n\t<p>Complete Steps 1\u20134 above and compare your measurement with the S\u2013XXL size chart. Because manual measurements can vary slightly, measuring 2\u20133 times may help you make a more reliable comparison. If you are still unsure, contact customer service before purchasing.<\/p>\n\t<h3>What If My Measurement Falls Between Two Sizes?<\/h3>\n\t<p>Nasal structure and comfort vary from person to person, so the size chart should be used as a reference. If your measurement is near the boundary between two sizes, consider both stability and comfort. You may also contact customer service before purchasing for assistance.<\/p>\n\t<h3>Is a Larger Gnasal Size Better?<\/h3>\n\t<p>No. Gnasal size should be selected according to your nasal structure and measurement result. A larger size is not necessarily better and may cause discomfort if it is not appropriate for your nasal cavity.<\/p>\n\t<h3>Is a Foreign-Body Sensation Normal the First Time I Wear Gnasal?<\/h3>\n\t<p>First-time users may need a short adjustment period. Start with shorter wearing periods and gradually increase usage according to your comfort level. If persistent pain or obvious discomfort occurs, stop using the product and recheck the size and fitting method.<\/p>\n\t<h3>Can Gnasal Be Adjusted in Width or Angle?<\/h3>\n\t<p>Yes. Gnasal features an adjustable internal support design that allows small adjustments according to individual nasal shape and comfort. Adjust gently and avoid excessive bending, pulling, twisting, or repeated deformation.<\/p>\n\t<h3>Can International Orders Use Taiwan&#8217;s One-Time Size Exchange Service?<\/h3>\n\t<p>Taiwan&#8217;s one-time size exchange policy does not automatically apply to international orders. International after-sales arrangements may vary by country\/region, sales platform, and shipping method. Please contact customer service to confirm the policy applicable to your order.<\/p>\n\t<!-- Final CTA -->\n\t<h2>Still Not Sure Which Gnasal Size Is Right for You?<\/h2>\n\t<div>\n\t\t<p>If you are still unsure after measuring, please contact Gnasal customer service before purchasing and provide your measurement result and country\/region.
