I made this imagining cocktails with sea glass. The frame size is postcard size. Please be aware that there may be minor stains or scratches on the mount (this occasionally happens). This is a hobby project by a complete amateur, so there may be some glue overflow. I use strong, quick-drying adhesive, but if any parts come off, please reattach them with your own adhesive. However, the air bubbles are only 2mm, so you may not be able to find them. Thank you for your understanding. The actual product is slightly brighter than in the photos. I feel like the photos make it look a bit dull. I am grateful to have connected with so many people. Thank you very much! (^○^)
