Vintage Box Of 12 Tubes Dur-o-lite 1.18mm Hb Refill Leads For Mechanical Pencil

Vintage Lot of One Box Containing 12 Sealed Tubes of DUR-O-LITE Refill Leads for Mechanical Pencils.
Each Tube is expected to have 24 short refill leads of grade HB (No. 2) and 1.18mm thickness.
The outside box in bad condition; ripped and dirty all around with traces of stuck old rubber, stains, etc.
To my quick inspection, the 12 sealed tubes are not identical in terms of font of prints, dirt on tubes and label, overall condition condition, etc.
I opened one extra tube I have (shown in the last two photos) and found there were 24 leads, each is 1.18 mm thick. The leads seem to be in bad vintage quality, but I do not have the expertise to confirm this observation. I will included this extra opened tube only as a gift, not as a part of the listed items in this sale.
Please be aware that I do not guaranty what so ever the contents in the tubes. Each tube is expected to have 24 leads of HB 1.18mm, but that analogy is not guaranteed. I do not guaranty any aspect of the content of tubes in terms of amount of leads, type of leads, thickness of leads, grade of leads, condition of leads, quality of leads, etc.
