Review (1/5): STOP TAPING THE CAPS DOWN!
Like many others this product came leaking everywhere! Please do not tape the caps DOWN! They are press and turn caps, they unseal when pressed......so why would you tape them in an unsealed position...... It did work great for whitening a seal spine, soaked for 3 days then boiled in the same 40 volume. This is a huge safety issue for customers and the shipping companies!
