These are the cutest things ever! And they come in cute little containers, Classic Sanrio style! The Pochacco erasers still have the wrapping but loose (I tried to use clear tape to keep on). See pics for approximate measurements. I’ve never used the erasers; there is a smudge on one of them see pics…just too darn cute. My childhood was all Sanrio stationary! So most items are considered vintage because they came from the 80s & 90s. They were so cute that I rarely used them; therefore many look amazing still. I couldn’t tell you how long this will last should you choose to use them, so they are sold as is…more for decor and nostalgic memory. They are perfect for the collector for sure :)
