Irregular shirts are sold as 12, 24, 36, or 48 pieces in a carton. (or more can be bought, please send an email to email@youruniformsource.com if this is the case.) You are guaranteed to receive a work shirt and the quantity that you ordered, but sorry special requests for size, color, long or short sleeve cannot be accomodated. What is most common is to receive a mixture of sizes, colors, fabric type, shirt style, and long/short sleeve. Though rare, each carton may contain all of one size, color, fabric type, shirt style, and long/short sleeve. Shirts may have embroidery, name patches, or company emblems with first and last names, or company names. Irregular/Second quality garments are defined as being off shade, uneven pockets, streaks in fabric, small stains. There are no manufacturing flaws in the sense that the shirt will fall apart. All sales are final-no returns or exchanges. Definitely contact us with any questions are email@youruniformsource.com.
