These are picks used for bento boxes and the like. They were stored for a long time in my parents' kitchen. I believe they are unused, but since they are quite old, I cannot be certain. The case is also cute, with a Showa retro feel. Upon inspection, they seem to have a certain degree of strength, but as they are very old, there may be undetected deterioration. Also, the sponge inside the case has some dirt (see photos) and there are scuffs. The item will be placed in a waterproof bag, wrapped in bubble wrap, then put into a kraft envelope and shipped via Yu-Packet Post. Please purchase with the understanding that these are vintage items. m(__)m #ShowaRetro #Bento
