When you send away for a news paper "Fantastic Offer" of plantlets (usually flowers), they come in teeny / titchy little black plastic pockets. While loading up another batch of insulin injector pens I thought the protective container in which the needles come is very similar.
A scap bit of wood drilled about an 1/8" through to stand them up, snip the narrow end of the clear plastic bit and
voilwar , tiny seed glowing thingies. But then you have to be or in contact with an insulin dependant diabetic to take advantage of this "Wonderfull offer"!
Cheers, Tony.
