Most Frog Mustard orders ship as regular letter mail in a yellow envelope. USPS may mark letter mail as “delivered” when it reaches your local post office, before it arrives in your mailbox.
Please allow up to 3 business days after the delivery scan for your order to arrive. In the meantime, check your mailbox, mail stack, and with family members or roommates. Our yellow envelopes can sometimes be mistaken for junk mail or bills.
If your order still hasn’t arrived after 3 business days, email us at hello@frogmustardstickers.com, and we’ll be happy to help.
Can I get a refund for upgraded shipping if it didn't arrive in time?
Upgraded shipping charges are not refundable for delays caused by USPS. Once your order has been correctly handed to the carrier, delivery timing is outside our control, and the shipping fee covers the service selected at checkout.
Exception: Priority Mail Express shipments may qualify for a refund from USPS if they arrive after the guaranteed delivery time. Refund requests must be submitted directly to USPS: Request Refund.
If the wrong shipping method was used for your order, please email hello@frogmustardstickers.com, and we’ll help make it right.
Why does my vinyl sticker or decal have small bubbles?
Small bubbles can sometimes appear in vinyl stickers or decals after packaging, shipping, or installation. This usually does not mean the vinyl is defective or the adhesive has failed.
After the decal is applied to a clean, smooth surface, minor bubbles often flatten on their own as the vinyl warms and settles. This may take a few days to about a week. You can gently smooth the area from the center outward using your fingers or a soft-edged squeegee.
For stubborn bubbles, gently warm the vinyl with a hair dryer on the lowest setting, keeping it several inches away and moving continuously. Avoid overheating the decal.
Large bubbles, creases, or bumps caused by trapped dirt may not disappear on their own. To help prevent them, apply the decal slowly and smooth it firmly from the center toward the edges.
Why won’t my magnet stick to my car?
Our magnets are strong and flexible, but they only work on clean, flat, magnetic surfaces. They will not stick to plastic, aluminum, fiberglass, or other non-magnetic panels.
Standard magnets are made with 20 mil magnetic backing. We also offer a thicker 30 mil upgrade, which may hold its shape better in colder weather. Please note that thicker magnets may look more noticeable on your vehicle.
Before troubleshooting, test your surface first.
If the magnet sticks to your fridge but not your car, your vehicle likely has non-magnetic panels in that area. Try another spot, such as the trunk, hatch, or doors.
If the magnet does not stick anywhere on your vehicle, your car may be made with aluminum or other non-magnetic materials. Please check compatibility before purchasing, as we do not offer refunds for magnets used on non-magnetic surfaces.
If your magnet is bent or curled, temperature may be affecting it. Warm it gently with a hair dryer or heat gun on low to make it flexible again before applying.
For best results:
- Apply only to clean, dry, flat surfaces
- Do not place magnets over plastic bumpers, badges, or decals
- Remove magnets regularly and clean underneath them to prevent dirt buildup and reduce scratching

What if my magnet bends or curls?
Magnets can bend or curl in cold weather or during shipping. If that happens, don’t worry — it’s usually an easy fix.
Warm the magnet gently with a hair dryer or heat gun on low until it becomes flexible again. Then lay it flat, let it cool, and reapply.
Do not place the magnet on your car while it is still bent or curled, since it may not stick properly.
