Thank you for viewing! These are parts that can be used for handmade crafts, etc. The size is approximately 3.5cm tall and 2.7cm wide. 2 green, 2 yellow These are imported products, so there may be some imperfections in the construction, but they are not very noticeable and should not affect use. They will be shipped in a leak-proof package with bubble wrap. I have set the shipping time to 4-7 days due to work, but if the timing is right, I can ship them in 2-3 days.
