Instant purchase is welcome. Price includes shipping, so no price reduction is possible. Purchased on Amazon for 1500 yen. Space around the mouth. Small size: 145mm x 95mm. 65 breathable masks. Wire in the center to prevent sticking. 3-layer construction. 99% cut filter used. Soft elastic ear loops. To reduce shipping costs, we will ship via Yu-packet Post. Due to the 4cm thickness limit, if it doesn't fit in the post, we will take it out of the box (unopened) and put it in a zip-lock bag for posting. Please refrain from purchasing if you are concerned about this. #SpaceAroundMouth #BreathableMask #OkudaPharmaceuticals #SmallSize #SoftEarLoops #MadeInJapan
