Glass glasses Tall, lightweight (subjective opinion of the seller) Transparent, with four colors at the bottom: pink, yellow, green, and black, one of each Diameter (bottom): approx. 5cm Diameter (mouth): approx. 5.7cm Height from bottom: approx. 14.5cm Colored glass, with color at the bottom. I think it's a tumbler, but I'm not sure, so please check the photos. Probably air bubbles from the manufacturing process, several in each. Photos of some of the noticeable black and green ones are included. One of the black air bubbles can be touched from the inside, so it appears to be a dent. The green one is out of reach, so the condition is unknown. There are long, thin oval air bubbles (less than 1mm) at the top of the black and pink ones. (I thought it might be a scratch, but I can't feel it with my fingers from either side, so I assume it's an air bubble.) These items have been stored for a long time in a wooden warehouse room. I can't bear to throw them away, so I'm offering them for sale. I have washed them, but due to the warehouse storage and to prevent breakage, I will handle them with bare hands. The buyer will be responsible for hygiene management, so please consider this only if you understand. Shipping will be either Yu-Packet Plus box or Kuroneko Yamato Takkyubin (home delivery) via Rakuraku Mercari, but both will be anonymous shipping.
