I've used this maybe two or three times in the last eight years? To inflate my kids' ball toys... Otherwise, it's been stored at home. Actually, I realized that a 100-yen store pump was sufficient, so it ended up being put away and didn't get much use. I thought it would be suitable for serious sports, club activities, and away games. It looks cool too. --- I have various other items for sale. Please let me know in the comments before purchasing if you'd like to buy items as a set. I'll deduct 200 yen from the total. --- --- Compact hand pump, convenient to carry. - Brand: molten - Model Name: Pentagon - Color: Blue - Type: Hand pump Thank you for looking.
