FYI For you guys in the United States maybe Canada Home Depot is selling 3 board bamboo sets for $7.88.
It’s a great deal. I bought a bunch last year and picked up 4 more yesterday. I break them up and engrave different stuff on them. Then I give or sell them separately.
You can sometimes find them on Amazon if your local HD runs out.
The Christmas Tree store had some small ones for a dollar each.
