## Questions & Answers

**Q: Do you apply these under, over or both?**
A: I think applying both is overkill and create “too much” a filter situation. One os plenty and usually on the outside.  But i do not know your intended use.  But again one is plenty and on the outside

**Q: Can they be reused?**
A: Yes.

**Q: Will they cover 2 in hole?**
A: Our stickers are only 2cm and can't cover 2 inches.

**Q: what is the material?**
A: No idea.  But its breathable. Seems like a poly.
