The absolute answer to shipping with usps. 600 cards shipped using these envelopes and zero returns! Hobby armor shell mailer, semi rigid sleeve, card, cellophane team bag and that’s all you need. I ship 5 cards in these at envelop pricing.
I ship 100% of my sports cards I sell online in these mailers. Could not be happier with their durability and performance.
The cardboard protectors are essential to my shipping needs and protect the cards I ship very well. My customers are always impressed with the level of professionalism that is included with my packaging and it's thanks to Hobby Armor.
These envelopes make my shipping so easy and professional looking. My customers are always impressed with how well the cards are protected using these Shell Mailer envelopes.
