ALL of our order now require tracking to guarantee delivery. Unfortunatley, I can no longer just ship basic envelopes because there is no guarantee they will arrive properly. Having tracking on all of my orders will GUARANTEE delivery. Thanks for your understanding. Each sticker comes in various different sizes. You can choose from regular or reflective material. Each decal is die cut and has a small layer of application tape over the top. Please remove this layer after applying your decal. If you are interested in customizing any of our decals, PLEASE send us a message on and well do our best to get back to you. Were always up for a few good ideas for our bumper stickers. You are guaranteed the best material, best product and best service. Feel free to message us on for any questions or special requests. Decals are shipped in rigid envelopes that have tracking information. I no longer ship basic envelopes as they cannot be tracked or guaranteed by Etsy. David...President/CEO
