Lengths are approximate and can vary slightly batch to batch:
14g is 2-1/8" tall. 12g is 2-1/4" tall. 10g is 2-3/8" tall. 8g is 2-1/2" tall. 6g is 2-3/4" tall. 4g is 2-7/8" tall. 2g is 3" tall. 0g is 3-1/4" tall. 00g through 1/2" are 3-1/2" tall.
These are all hand made and matched the best they can be. Each piece will vary a bit as it's impossible to have two identical pieces.
14g, 12g, and 10g are extremely fragile, please wear and store with care!
