These are 7mm cat safety eyes in bright blue with metal washers to hold the eyes in place. This product comes in sets of 5, with ten eyes with posts on the back and ten washers to fit on the back of the posts.
These safety eyes are not locking. to lock them safely in place I recommend applying super glue to the back for a stronger hold.
Please allow some slight variation to size as some batches may be slightly smaller or bigger.
The 7mm cat safety eyes are easily installed without tools. These are not meant to be used by children. These are very small pieces that could be swallowed.
I like to use these eyes in making very small felt dolls, and several of my felt animals.
