⑬ 18mm, a pair of light gray-blue flat oval paperweight glass & plastic eyes. The eye size is the diameter including the white part of the eye. Made of glass and plastic resin, it's reasonably priced, but the important pupil part is delicately crafted like a real eye. Being vintage, the iris seems to have more detail. Please check the images for the overall size, etc. The condition is good for an antique. Please check the images as it has aged. There is age-related wear. Offered at a low price. Please refrain from bidding if you are overly concerned about details. The item itself appears to be clean. There is no guarantee for postal accidents or non-delivery, but shipping is planned via regular mail (unregistered). Thank you for viewing.
