About heat exposure

Due to the material's properties, exposure to heat or direct sunlight can damage or deform your case. We strongly advise against leaving it in such conditions

The silicone band is too tight/loose

Our silicone bands are designed to hold the reeds securely, so after using looser bands, you may need to get used to applying a little more pressure when inserting the reed into the slot. You might also want to give the silicone a little more time to mold to the shape you need.


It’s also possible that the bands are simply too narrow for your specific reeds. If the problem persists or you find that the slot itself is too narrow, please contact us and we will make a replacement band.

The lid is too tight/loose

You can carefully adjust tightness by turning the screw. For the time being Hexagon M3 are being used in our products.
