The top pair in the first photo are very similar to Slip n Snip scissors, however, they are not marked. The blades are stainless steel and still sharp. The handles show scratching from use. They fold up very easily.

The bottom pair are stamped CHINA on one of the handles. There are some markings stamped on both sides of the base of the blades that look like Chinese writing. See the photo for more details.  This scissor also folds up very easily and also has a hole punched in the handle so that a chain could be added to them (sort of like eyeglasses chains) so that they can be hung around your neck.

The Slip n Snip type scissors measure about 4" and the other scissors measure 3 1/4" when open. Thanks for looking. Email with questions. Offers welcome.
