Description: These are vintage solid Pyrex glass stoppers, size #29 dialhead, Pyrex No.7661-29. These heavy ground borosilicate glass stoppers are used for air/liquid tight seals when paired with their corresponding ground joint, often for hazardous, or volatile (or otherwise) chemicals/solutions. These were salvaged from a retiring lab and seem to be well taken care of, they're essentially new. Seems like they were either never used, or used carefully a few times and then kept in storage. There's no chips, cracks, scratches, residue or discolorations, should be perfectly functional. I did some modest dust cleaning with glass wipes. The walls of one are a little less frosty, but this shouldn't affect the function. Just let me know if you'd like any more pics or vids. All in all, I think these heavy duty stoppers are great and deserve to return to service. I personally inspect every one of my glass stoppers closely, cuz I personally hate chipped stoppers... I've cut myself by accident before. If there's wear, I will say so and show you. I tried to be transparent in my pics, largely bc other sellers usually only offer 1-2 pictures & conceal small chips in their pics and descriptions. If I missed one or you're otherwise dissatisfied with what I send, just message me and I'll get you replacements! Thanks for reading. May your Science be significant! -Sean
