I ordered at Nightingale Nursing Supplies, the Supplier from D was at that price at that time not available. Goods come in several packaging units of 20 pieces. The delivery took place in a padded envelope, this was probably somewhat compressed during transport. Some of the cones are therefore no longer usable. Nevertheless an excellent price-performance ratio. "Not for Resale" is merely an attempt by the manufacturer to keep the packaging for the clinic needs by general market away. The pieces fit and the measurement results are also ok (the first measurements with the goods checked by "old-fashioned" control measurement). For delivery time (10 days from the UK are too long. Ok, maybe I read the notes when ordering) and transportation damage, there is a star deduction (although that has nothing to do with the actual product). The product we will buy again.
