I was really surprised with the good quality finishing of this product. The cap fits very tight in the tube that seals very well.

These plastic laboratory test tubes are perfect. Can't say anything else. I use them for 'small parts' storage like tiny screws and nuts, tiny smd leds etc... wil buy them again! I already bought smaller ones. Happy with the buy.
