Where to find cardboards for sports cards shipping ?

[jaydee12321]

Hi,

I would like to ship my sold sports cards with a very thick piece of paper like that one on the photo below.  Tried to find some on eBay with no success.

Does somebody know where I can find such shipping material ? Thanks

I've been using Bags Unlimited dot com (Rochester, NY) for shipping supplies since my early days on eBay. However, I don't believe you will find chipboard or filler pads made in that size, perhaps you can customize an order. If you're buying in bulk, their prices are often cheaper even with customs, freight and tax than purchasing from Cdn ULine.
