about 1/2 way down the page. You can order it in hollow sticks or solid sticks. For you sizer, you prolly want the hollow sticks. You can also get them in hard plastic containers or ziploc baggies (the latter is cheaper). When I order, I order whatever fits in a flat rate envelope. Good stuff...you wont be dissapointed.
