This scale is used but is in great condition. There may be some minor scuffs from use. There is not a 6VDC adapter included but one can easily be purchased. 

Some information from online:

The Brecknell 6720U scale gives any sell-by-weight retailer a sturdy and reliable method of reporting item weights during checkout. Available with multiple capacities, the 6720U is great for products large and small alike.

The 6720U is a little larger than the 6710U, giving you a greater base for weighing larger products, such as boxes or large bags. At 12" by 14", the 6720U has a wide platter and sturdy weighing base. The scale is available with two capacities: a 15lb capacity for delis or candy shops, and a 30lb capacity for corner grocers and sellers of heavier products. The 15lb model provides additional precision, ideal when selling expensive products. Both scales can be modified to sell by "count," taking the weight and converting it into a pre-calculated number of items.

To handle such heavy weights and repeated use, Brecknell used high quality components in the scale's construction. A heavy duty cast aluminum X-shape support holds the scale secure, while the stainless steel platter is built to survive less than gentle use.
