Other Potential Resources:

* Local Printers: Local printing companies may be able to help you with custom mailer design and printing.
Tips for Finding the Right Supplier:
* Specify your requirements: Be very clear about the size, material, finish, and quantity you need.
* Request samples: Ask for samples of the material and printing quality before you commit to a large order.
* Compare prices: Get quotes from multiple suppliers to ensure you are getting the best price.
* Consider shipping: Factor in the cost of shipping, especially if you need to ship the mailers to your customers.
Additional Considerations:
* Matte vs. Glossy Finish: Matte finishes are less reflective and can give your mailers a more sophisticated look.
* Rip-Tab Closure: Rip-tabs (or hook and loop closures) provide a secure and easy-to-open closure for your mailers.
* Hard/Rigid Mailers: These mailers offer superior protection for delicate items. They are typically made from corrugated cardboard or plastic.
Remember to carefully review the supplier's terms and conditions before placing an order.
