So this is something that I got pretty excited about when I got the sample.
This is a fantastic replica of the M1917 Eihandgrante. This was designed as both an offensive and defensive grenade and is literally the size of an egg with a fuze. The concept was that a grenadier could carry many of these because of their size.
Made of resin, these are for display, but can be used for reenacting. I would not recommend throwing these very hard, but once you buy them, they're yours to do what you want.
Wait time on shipping on this item is approximately 1-2 weeks. If these get popular, that will change and get shorter.
NOTE: These can NOT be shipped outside the U.S. even though they are resin. I'm sorry, but I can't risk getting in trouble with customs over these.
