Thinking about using a box or padded envelope? Why not use a lightweight yet robust Tyvek expander envelope instead? Available in a range of sizes, these envelopes side expanders open wide to accommodate heavy and bulky items. Expander envelopes not only save you postage costs, they also save you packing time. Just stuff and seal. You can do away with adhesive tape and string!
