32 Shim-It 8" Engineered Wood Composite Shims. Resists splitting, splintering, swelling, warping, and twisting. Nail, cut, and snap off better than solid wood shims. 100% usable, impervious to insects. No rot or waste. You will receive 2 packs of 12, plus an additional pack that will have 4 of the 12 removed so that they will fit in a small flat rate priority mail box. To send the additional 4 shims at the USPS parcel advantage rate would cost an additional $3.00.
