I like that these can be used as a regular dual form and also as a sandwich form. Gels apply easily and the forms pop off with no problem. You do need to apply a small amount of peel off base coat to the bottom tip to hold it under the nail for the application process. If your nails aren't long enough to do this with, you can try two methods: either use the top portion as a regular dual form or find a snug fitting bottom portion for each finger. This option doesn't guarantee a great fit and there may be gaps, so keep that in mind. These forms are well made and durable, so each can be reused over and over again. This is great if you're trying to cut costs. There are a lot of sizing options in this set, too, so anyone should get a good fit. The plastic can be filed or trimmed slightly for a better fit.
