• TYVEK SUB 14 • OPEN END (“catalog”, opens on short dimension) • PEERLESS TAC™ Flat, plain Tyvek® mailers are great no-nonsense envelopes for mailing practically anything that you can fit in a flat envelope, where strength and light weight (to reduce postage costs) are a factor. You can avoid printing your return address by using labels that you already have. We highly recommend sub 11 (when available) as anything heavier is usually overkill. Want it printed?
