Cryptube

## Cryptube

This tube cover secures your mnemonic phrase. You can insert 4 characters of each word onto the steel washers.

### Note

This tube cover is plastic and therefore is not resistant to heat or fire. Because of this, we are inserting several steel parts into the model.

If you want to secure the cap of the model, you have to drill in a bottle cap hole with 6mm (for 10mm model) or 4mm (for 8mm model).
