We use lead-free solder, which is safer and more expensive than regular solder. -------------------------------------------------- There is a scratch on the blue glass. It is believed to have occurred during the glass manufacturing process, but it is quite noticeable, so the price is reduced from 3,480 yen to 3,080 yen. The included photo frame is just a bonus. ※ There may be streaks or air bubbles in the glass that occurred during the manufacturing process. ※ Although it was just made, the Showa glass used is a used item. ※ The actual product may differ from the image due to lighting conditions. ※ This item was created as a hobby, and there may be slight differences in glass size or misalignment. Please understand that returns, exchanges, and cancellations are not possible after purchase, so we appreciate your consideration. ※ The soldered areas are polished with poly wax, which has an anti-rust protective effect, but a whitish rust characteristic of stained glass may occur. You can enjoy the antique look, but if you are concerned, wiping it again with poly wax will make it clean. In that case, rubbing the brown solder parts strongly may cause the color to fade. Please be careful.
