These glass eyes can be used for crafting handmade animals (cats, dogs, frogs, etc.) using materials like wool felt. This listing is for two sets of 2 eyes each (4 eyes total). Please refer to the fourth photo for the shape of the glass eyes. ◆ Glass Eyes: Approximately 18mm in diameter, hemispherical type. ◆ Color: Red (as shown in the photo) ◆ These have been stored privately, so there may be some creasing on the backing paper and minor scratches on the glass. Please refrain from purchasing if you are looking for a perfect item or are overly concerned about minor imperfections. ◆ The backs are not the insert type, so you will need to cut them and attach them with glue or another adhesive. The eyes will be packaged in sets of 2 with bubble wrap, and then the two sets (4 eyes) will be placed in a waterproof bag for shipping. Please refer to the photos and purchase if you are satisfied (the items in the photos will be sent). Immediate purchase is OK. Bulk purchase is OK. We do not sell individual eyes in quantities less than 4, so please be aware of this.
