Inflatable Ice Cream Cones, Ice Cream Blow-ups, Party Decoration, Party Favor, 12

I bought these to give out as party favors. I blew them up right before the party started. 6 out of the 12 deflates. I ended giving away 8 as 2 party guests insisted on taking home the deflated one. It was quite embarrassing. I wrote the seller asking for a partial refund, he wrote a long message back stating there nothing wrong with them (see my photo. This is taken 5 min. after inflating. Within 15 min. they were flat). They have all have been tested. He suggested putting a piece of tape over the nozzles as that is what he does to solve these problem. I would not recommend this seller!!
