This is a HARIO Lampwork Factory necklace, "Mist." I purchased it and stored it without using it. I believe it is a discontinued item, as I couldn't find it on the online shop. I think it cost around 4,000 yen. The diameter of the glass head is approximately 15mm. Please refer to the photos for the chain length, as it's difficult to measure. It comes with a box and a card that looks like an instruction manual. I plan to ship it in a Takkyubin Compact box. I don't recommend it because it's delicate and fragile, but if you only want the necklace and not the box, I can ship it via Nekopos. In that case, I will deduct 240 yen from the shipping cost, so please let me know before purchasing. I have a cat, so I may not be able to completely prevent cat hair from getting mixed in, even with care.
