A HUGE can't-miss-it pin with a pastel crayon style rainbow background and black hand drawn lettering that reads "my immune system is compromised. No, you can't catch my autoimmune disease, but your common cold can make me dangerously unwell." Seriously. We gotta start thinking with our brains. This awareness pin is HUGE, so will hopefully catch peoples' eyes and raise their awareness too! Even if it's "just a cold". Before you buy this, please just be aware of the size - I'm not the one who's gonna look like a right plum when you leave a weird review saying it's way bigger than you thought it'd be. These pins are 75mm (3") in size aka frickin' huge [see photo with English 5p, which is roughly the same as a US dime] and have a metal back with a sturdy pin across the back. If you choose to get a magnet (if the option is available) then you'll get the same metal back - no pin, strong magnet affixed by yours truly. ♡ SHIPPING + PROCESSING ♡ All my items are made in house, by me, and they are all made to order (except enamel pins, which are the ONLY "in stock" item I have) - I'm only one person so please be patient. :) Your order is never tracked unless you upgrade at checkout, please do not message me asking for tracking info if you didn't upgrade. I don't use plastic packaging (or if I do it's recycled/recyclable). The service used to ship your order depends on where you are and what you order. Please see my FAQs and policies for more details.
