Have you seen the crimp-it or whatever it’s called. Same thing but not a toaster, could use it to prepare them before your session and then just pop it in a toaster device if you’re choosing to heat it up.
Interesting to look at RM as a business. A redesign of a toaster device, simple and easy, has propelled them in to what they are now. Goes to show how something incredibly simple can lead a business to be extremely lucrative!
