The maximum running time of this plastic classroom sand timer is 60 minutes. In some cases, it is enough for kids to use. If you need more running time, like 120 minutes, please check the large size of the plastic hexagonal hourglass.
Popular Running Time: 1 Min, 5 Min, 10 Min, 15 Min, 30 Min, 60 Min.
We can put a sticker in the middle of the caps.
For this plastic sand timer, the regular packing is to put each hourglass into a PE bag, then put it into a box. The sand timer itself is already safe enough.
For other general information like the samples, shipping, payment terms, please check the FAQ page. There are great answers.
As a factory since 2002, we can have some cases for your reference and hope they can do some help.
(1) About the Color
We will match the color of the sand to the color of caps. Most of the plastic sand timers with caps will be done in this way.
