These inserts are invaluable to me for easy ID of clinical samples. Inserts fit easy onto the top of the cryogenic tube caps and stay there forever. The product is great, but expect to wait for over 2 weeks from ordering to receiving the product.
Pros: Fit extremely well on top of tube, easy ID of samples
Cons: the time it takes from ordering to receiving the product
