It fit and it shipped!
After looking for a reasonably priced, strong plastic mailer for garments, I found RoyalBag. Bags are well-built at a strong 2.5 mil with a perfect matte gray surface for slapping on postage labels and our business logo. All was shipped quickly!
Other online companies produce mailers at lower prices, but their products are made with thin unreliable plastic. Another very well-known company produces great products, but their prices are relatively higher.
RoyalBag is in the bag for our shipping needs! Thanks.
