Yes, our stencils are made from low tack vinyl and they are reusable with care. Just as long as you don't rip them off the model roughly, they can be used multiple times. Simply place them on the backer sheet in between uses. Even when the tack wears off, you could always use masking tape or blue painters tape. We've had customers say that they've been able to reuse them up to eight times.
We're also working on creating stencils made from different materials which we plan on releasing in the near future. If you sign up for our newsletter, you'll be notified when we release new products through Chapter Customizer and Fallout Hobbies.
