There is no difference between the Standard and ones with Additional Donations. The additional donation is just that - it help us fund alert whistles to be donated to organizations. More info at AlertWhistles.com
In the event you do one of the ones with an additional donation, please make sure you fill out the donation form on AlertWhistles.com so we can recognize you on the website as well.
these whistles are made to order and will take 1-2 days to print before shipping out. For the custom text, it's 1-2 days after we confirm the custom text that you want.
The custom text one includes the donation and allows you to customize the text on the whistle. We will email to confirm the text you want and a proof before we make your whistle.Each side is limited to so many characters due to limitations of what the 3D printer can print legibly. We recommend 12 or less characters; however up to 14 characters can be done & up to 2 lines of text per side. Currently we only use the one font as it's easiest to read: Arial Rounded MT (as seen in the photos)
