They are mailed via first class mail in a bubble mailer. Note, these cannot ship with a postage stamp because they are inflexible and would break through the mail sorter, therefore they are set at the lowest possible postage rate for a small package, which averages about $3.50. Given the weight is only set at 1 oz on the site, small items that you combine with this order should still only ship for the one rate of $3.50. This includes all my magnets, stud earrings and similar small items so you may want to consider upcoming birthdays and holidays for other small gift items to maximize on the shipping! Just a tip since the shipping is on the higher side for just a single item (sorry, USPS is the big boss here….). Also note, first class mail does not include insurance, just tracking. If you want insurance, you can purchase supplemental insurance at checkout or just have it shipped priority mail which includes tracking and $50 in insurance.
