Diodes in a convenient box, just did not look that they are 3mm all, well, this is my pass, work correctly, Green only I would like to brighter, and then they are like ordinary indicators, the rest of the colors are bright, in the photo they are in the backlight of the clock

Ordered on January 18, received on March 11 in Ukraine. Very long sent, wrote to the store, he replied that because of the virus can not send, but still after a while sent, the evaluation reduce because of this will not be, still, the virus is not a joke. According to the product I will say the following: came in an envelope with purple, the case is a little different (not as in the photo), all the whole. Recalculate the amount completely did not become, counted only one color (exactly 100). Regarding the work, checked each color on 1 Diode-work. All shine bright, except yellow and green (like dimmed light), used a resistor 0,25W-1kom. Conclusion of this: you can take the goods of norms

Arrived, although after the end of the warranty period Ali, but so all the last parcels, this is apparently our post office. LEDs shine, they are not ultra bright otherwise would be more expensive, normal indicator. Thank you for the goods.
