I'm sad to say that at this time, I have to issue a warning for the Redbubble masks. It's in their description on the site, but I'm giving a bit of information here about why I'm doing this.

Redbubble has given conflicting (and imo possibly intentionally confusing) information about the safety of their masks. From what information is available now, it's my understanding that they are safe to wear for fashion purposes only. For this reason, I've raised the prices of the masks to the standard 20% markup for artists instead of what I had them at, which was 5%. I lowered the prices initially because I wanted to encourage safety and make it at least a little bit more accessible to people. (The reason I didn't initially lower the prices to a 0% markup was because I've also suffered from the repercussions of coronavirus and am struggling financially, so I do still need to make money somehow.)

I got my information from the useful comments here, which are at the bottom of the page.
