"Gorilla" Stamp..leather Press Tool DELRIN..NOT A HAMMER TOOL. 1 ½ inch
 
This tool is meant to be used with a press...not a hammer.
 
Makes a nice impression 
 
Stamp is 1 ½   inch squared...3/8 inch thick made from Delrin
 
Veg tan leather is the leather of choice for embossing.. you case "dampen” the leather with a wet sponge " don't soak the leather...if it's to wet it want leave good details. I know leather presses can be pricey... I found a decent one at Vevor I use.
Quarter is just to show the size for comparison.
 
five pounds of flour makes a mighty big biscuit...
Have a blessed day.
