HI, if you are still experiencing problems, you can also use Nail Prep as this also creates the perfect base for Minx. Sometimes, usually when there is very little nail present, it can be difficult to get Minx on to little toe nails. However, in this instance, it doesn't sound like this applies. Make sure you do not touch the Minx to your skin, always use a pair of tweezers or the end of your hoof stick to 'pick up' the Minx from the backing sheet. Also, if you have applied the Minx, it hasn't stuck as expected and you have re-tried the adhesion is going to be compromised. Because you've then used a new set of Minx this also cancels out that theory but it may have also made the new set of Minx not adhere either. Sorry, not trying to teach you how to suck eggs, but hopefully some of this has helped. :idea:
