## Questions & Answers

**Q: Is it a normal rubber band or the blue on with Fermentaholics branding?**
A: This item comes with 4 normal rubber bands and one with the blue Fermentaholics branding (5 total rubber bands). If you have a specific request for one over the other, feel free to reach out and we can customize it for you! Cheers!

**Q: Will this fit a 10 liter crock? Please do not answer unless you have measured**
A: The squares measure 10 x 10 inches (or 25.4 x 25.4 cm) so it depends on the size of the opening of your 10L crock. You will want enough room for the cloth to hang over the sides and allow them to be secured by the rubber band. The typical opening of a 1-gallon jar is about 4 inches (10.16 cm) and these allow for more than enough room.

**Q: How many inches long is the rubber band? Please do not answer unless you have measured the rubber band.**
A: laying flat 1/2 of it measure 3 3/4”

**Q: What size are the rubber bands?**
A: Big enough to fit over my gallon jar mouths?
