Set of 11 long ones which are 8" long, hold about 2.4 fl oz volume and 2 short ones which are 6" long and hold about 1.8 fl oz volume.
From ED Luce originally. Full price is 1.00 and .90 each. pretty sure this is a perpetual stock item, great way to try it out and you will have the rack which is the biggest expense of course!
Stainless steel rack is perfect for retail, looks snazzy, and definitely handy for working with these tubes even if you don't need it for display!
Tubes are perfect for packaging powders, clays, of course salts. a few of the long ones were used to hold seaweed powder - all have been washed and dried but there may be spotting as i don't have a dishwasher. a nice polish will set them right!
The rack is 11.5 x 5 inch surface, 3.5 inch tall, holds 24 fat test tubes. i bought it on ebay for $40 and the seller shipped it in a mailing envelope. no padding, so it's bent as you can see. i just kept that side to the wall. i'm wrapping it into the price of the tube set (i figured $12 for the rack and .50 each for the tubes) Not selling separately, sorry.
i can try a flat rate USPS but i don't think it will save money, let me know if you think otherwise!
