Tri-Stubby not included. A set of buttons includes 1 of each design.
These buttons are specifically made to compliment the AngrFish Tri Spinner from Rotablade, but will fit many other spinners. There is the option to upgrade your piece with hand engraving along the rim if you'd like...pictures coming.
Buttons are 20mm in diameter, with a 6mm space between them. Buttons are stainless steel with a coin of your metal choice set into the button.
