The dummy replica of a F1 grenade is made of rubber outside with a metal weight inside. Weight the same as the original about 0.5 kg. An ideal replica for training uniformed services, scouts, reconstruction groups, in a distance throw (event companies) as well as for a "bomb" gift.

The replica is made of a flexible, durable EPDM (ethylene-propylene-diene rubber) rubber compound, and is characterized by:
- high resistance to aging and weather conditions, ozone and UV radiation
- resistance to organic and inorganic acids, cleaning agents, potassium and sodium alkalis
- maintaining its properties in the temperature range from -50°C to +130°C
- flexibility and susceptibility to stretching
- good memory of the original shape
