" popup. Bought these sucks for my 3yr and she loves them. I also have the older model that sound a bit warmer. Bob good Honestly not bad for a $10 tank top. I couldnt wait to get home and take them off! Still quite elegant. Please keep in mind my shoes are tiny (size 5 women) this item would NEVER be able to hold mens or larger sized shoes. Due to this reason, I only use it on severe nights where my dry mouth keeps me from sleeping, probably 2-3 times a week instead of every night. Acceptable at this price range.
