Normally you see some microneedle eye patch on the market very cheap , maybe only one dollar, but their needle shape are surely looks like a mountain,sharp on the top but bigger in the bottom, not easy to stick in skin totally. But ours, why expensive? Because our needle are not like mountain shape, ours looks like a bee needle, slim and long, easy to stick into skin competely.

The needle is very easy to destroy, its sensitive to humidity and temperature. So we can not put desiccant in it. So we upgrade the plastic holder, stronger and seal well.
