Enter 12 in Quantity to get 50% discount off of 12. These stakes are made from quality Baltic Birch 1/8" plywood, which is not the cheaper home store plywood.  I have over 80 varieties in stock, and can make anything that I don't currently have. Just send me a list of what you're needing. They are not sealed, and should last a full season, and probably two if taken out and dried flat at the end of the season. Some people do seal them to extend life. Measures .8" wide by about 7-1/2" long.
