The one and only "travel sweets" we fill our glove box with are Simpkins.. Made in the UK.. but available here in Canada in fewer and fewer stores.. wahhh LOL.. love them! Bought several tins last trip to England. .but they are all gone now..
Google Simpkins Travel Sweets.. they are a boiled, hard, fruit candy..small round tin, and covered in icing sugar (or at least a fine powdered sugar).
If Simpkins aren't the ones.. just check "travel sweets" on Google.. and look at "images".. easier to check to see yours!
HTH... Kym
