RETURN COSTS & RESTOCKING FEE (NON-ASSEMBLED ITEMS)

There are no restocking fees. However the cost of the return shipping label will be deducted from your refund ($7.5 for small/lite packages, $13 for standard size packages, $15 for non-standard size packages such as golf shafts), if you decide to use the label provided by us. If you purchase a label yourself from a local carrier office (ie. USPS, UPS, Fedex), then there will be no deductions from your refund. If the returned items are not in new and unused condition, we reserve the right to dispose of them or return them to you at your expense. You may purchase return shipping if you would like the items sent back.

RETURN COSTS & RESTOCKING FEE (ASSEMBLED ITEMS)


🚫 No Returns or Refunds on Assembled Shafts

Please note that all assembled shaft orders are final. Due to the custom nature of this process, we do not accept returns or offer refunds on any assembled shafts. Each order is built to your specifications, and once assembly begins, we are unable to restock or resell the components.

We encourage you to double-check all specs (flex, length, grip, adapter, etc.) before placing your order. If you need help confirming details, our team is happy to assist before you check out.


Returns can be made on non-personalized items and non-assembled items within the US, 60 days after you've received the original order. Items are only accepted on unopened and unused products. Items must be returned in the original packaging.

 

INTERNATIONAL RETURNS

We do not accept any international returns at this time.

At Grips4less, we strive to provide a smooth international shopping experience. To ensure clarity regarding shipping, duties, and returns, please review our policy below:

Duties, Taxes, and Import Fees

  • International orders may be subject to duties, taxes, and import fees imposed by your country. These charges are the customer's responsibility and are determined by local customs authorities.
  • If duties and taxes are not paid upon delivery, the carrier may be unable to complete the shipment and may return the package to us.

Refused or Unpaid Shipments

  • If an international order is refused or the required duties/taxes remain unpaid, the carrier may return the package to us.
  • In such cases, customers will be responsible for all shipping costs, including outbound and return shipping fees.
  • Refunds for returned shipments will be issued minus all incurred shipping fees.

Lost or Delayed Shipments

  • Once an international order has shipped, we are not responsible for delays caused by customs processing or other carrier-related issues.
  • If a package is significantly delayed, we encourage customers to contact their local customs office or the carrier for more information.

By placing an international order (any order shipped outside the US), you acknowledge and agree to the terms outlined in this policy.

REFUNDS

Refunds are normally processed back to the original account (ie. credit card or PayPal). If you prefer store credit, please include this note of the refund request.

HOW TO CREATE A RETURN (ITEMS RETURNED MUST BE IN NEW & UNUSED CONDITION)

1) Access your order history, and request a return here

2) Your return request will be responded to within 1 business day (not including Sat/Sun/holidays). If the request is approved, we will e-mail you a return label. 

3) Package up the original order and drop off the package at your local carrier.

4) After 1-2 weeks after receiving the return order, we will process and issue your refund (original paid price of items returned minus cost of return shipping) to the original payment account.

DID WE MAKE A MISTAKE?

If there was an issue with your order (the wrong was delivered, or the product arrived damage due to carrier neglect), we will ask you to send us some pictures. If the item is confirmed to be incorrect, we will provide a return label to send back the items. Once the items are back in our warehouse, we will resend your order with the correct items. We cannot ship out a replacement order until the original items are received back. For damanged items, we will open a claim with the carrier, and once the claim is approved, we will send the replacement item. 

CANCELATION REQUESTS

While we do our best to process cancelation requests, our shipping team works fast, and we cannot guarantee that your order will be canceled

If we are able to cancel the order for you, there will be a 5% restocking fee deducted from the refund.

RISK OF LOSS

All purchases of physical items from Grips4less are made pursuant to a shipment contract. This means that the risk of loss and title for such items pass to you upon our delivery to the carrier.

RETURNS, REFUNDS AND TITLE

Grips4less does not take title to returned items until the item arrives at our fulfillment center.

Who It's For

Good fit if you...

  • Want a mid flight with mid spin: Mitsubishi rates the TB mid launch and mid spin
  • Have played and liked a Diamana Blueboard
  • Want a very light 51 g shaft in X flex, or a 74 g shaft in S
  • Are a club builder or DIY builder who needs an uncut shaft

Not the right fit if you...

  • Need R or SR flex, or a 50 or 60 series: we sell the 40 X and 70 S only
  • Want a lower flight with less spin: Mitsubishi rates the Diamana WB low launch and low spin
  • Want it ready to install in an adjustable driver or fairway: get the assembled Diamana TB

How It Plays

Consistent Feel Design. Mitsubishi keeps butt size, weight and balance point close across the whole TB range so a fitter can change weight and flex without a change in feel. The Xlink Tech resin system raises the carbon fiber volume for feel and strength, MR70 adds strength, and boron fortifies the tip section.

Mid launch, mid spin. Mitsubishi rates the TB mid launch and mid spin with a mid/high kick point and a medium+ butt, firm mid and medium tip. The 40 X weighs 51 g with 5.9 torque; the 70 S weighs 74 g with 3.4 torque.
