Description
Keystone Tablet is a 304-grade stainless steel seed phrase backup solution designed to protect your cryptocurrency recovery phrase against fire, water, corrosion, and physical damage.
Durable Construction
- 304 Stainless Steel — Built from high-quality 304-grade stainless steel, the Keystone Tablet is completely waterproof and resistant to various types of corrosion.
