Probe Tips:
The majority of our probe tips come in small hinged plastic boxes measuring approximately 2.2” wide x 1.7” deep x 0.4” thick (5.6 x 4.3 x 1 cm) and hold 5 or 10 tips. 12 of these boxes fit comfortably, with appropiate cushening by bubble wrap all around. Larger probe tip packages.will still allow to ship 8 or - worst case - 4 boxes at a time using this flat rate box.
Or we can  ship in the same box up to 300 tips in a bulk pack, of same or different type, 100 tips per version.
There is no tracking on Flatrate boxes. Consequently we need payment by Moneybookers or bank transfer.

• On payment with Moneybookers we will give you an additional 3% discount on the total. That is on top of lower shipping cost when using the Flatrate box.
• Minimum order size on bank transfers is $6000: Our bank charges us for incoming transfers from outside the US and other banks involved in the transfer typically deduct some amount without any documentation.
