Jamainspeedx Size Guide

On the online marketplace, we do not have a universal size guide available for both our sellers and buyers. However, we have developed a size guide template for sellers, which we encourage them to adopt. We require that every seller who sells products with different size variations, must include the picture of the size guide they adopted during production, when listing the product on the online marketplace. And also attach a size  label to every product with size variation before handing it over to us. Failure to comply with this requirement will result in the rejection of the product. Select the appropriate product type to display the corresponding size guide below.
