Lid diameter approximately 6.5mm, height approximately 5.5mm. New, in box. I purchased this but am selling it because I won't be using it. Authentic item purchased by myself in Tokoname City. Please refrain from purchasing if you are overly concerned about details. I may be slow to respond, and shipping may take some time, but I will ship as quickly as possible. First come, first served, even during negotiations. This is a flea market site, so please refrain from purchasing if you are looking for perfection. As it is stored at home, there may be overlooked stains or dust.
