BUT almost nothing is packed in tens
Err, I think they are...
List of things packed in base 10 multiples:
*** edited to reflect reality where I live ***
NEVER 10 except as noted below
*** Light bulbs - nope, usually 4 or 6
*** Eggs - nope, usually 12 or 18
*** Screws - nope: 3, 4, 6, 10, 12, but also 25, 50 & 100
*** Chocolate bars - nope, usually 6 - (trust me, I KNOW this one!

*** Small bottles of water - nope, usually 6, 12, 24, 36 and sometimes 48 half-bottles
And just for fun, my list of things packed in base 12 multiples that I could think of quickly:
Eggs - 12 or 18
Hot dog buns - 8 or 12 (and yes, the dogs are usually packed in 10's but some are now packed in 8's)
Wine
Soda Pop - 6/12/24/36
Beer - 6/12
Facial Tissue (box) - 3/6/12
Toilet Paper (rolls) - 6/8/12/18/24/36/48
Cans of Vegetables/Soups/Fruit - 12 per case
Paper towels - 6, 12, and more
Bars of Soap - 3, 6, 12 and 24
Nitrile gloves - oddly enough 100 to a box but 12 boxes to a case?
Leather work gloves - 3, 6 and 12
Socks - 6 pairs
Men's briefs - usually 6 pairs, but often include a 'bonus' pair
Men's socks - usually 3
Pens - 12
#2 Pencils - 12

Halls cough drops - 12, 20, 30, 180
Trash bags - 12 plus many other qtys. divisible by 10 or 12
Alkaline batteries (AA, AAA, C, D, and 9 volt)

Disposable diapers
Christmas ornaments
Motor oil - 6
Jello - 24 or 30 packages to a case
Ears of corn - dozen
Fresh cookies - dozen
Cupcakes - dozen
etc...
Just making a point that here in midwest USA more/most household items are still sold or packed 'by the dozen' than any other system. I don't know how long - or IF - things will take to move totally to base 10, but I won't be holding my breath.
Besides, being a computer guy I think they should all be Hexiecimal anyway...
