Years ago I modified a piece of Salamander Designs Synergy furniture and as a result ended up with two spare SA/S1 shelves. That was in 2006 and I don’t recall to what extent they’ve been used but they are in excellent condition and have been in my garage in a Salamander Designs box for years. No damage or scratches of note. One side on each one even has the plastic that peels off. Dimensions are 19.68 " W x 0.75 " H x 17.56 " D Will ship in Salamander Designs box with plenty of padding (these will ship with more padding than shown in the photo). These usually sell for $99 each. Very best, ThisGoes211
